Cats Communicate by Smell – Semiochemicals in Cat Communication

Posted on by felinepurrspective_u3q4o6

Cats have many more odor sensitive cells in their noses than we humans do. They also have a vomeronasal organ (VNO) in the roofs of their mouths to process odors. Cats communicate by smell.

This post was originally published May 2, 2021 and has been updated to reflect new content.

For a cat, odors can be associated with a particular place or individual animal, identifying that place or animal.

Another way cats communicate by smell is through semiochemicals. Odors can contain semiochemicals, molecules that carry “messages” from one organism to another. The organism receiving the “message” responds with a change in physiology or behavior. For example, there are insect traps that use hormones that simulate the type of scent produced by the female insect. Male insects are lured into the traps, preventing them from mating.

Semiochemicals that carry “messages” between members of the same species are called pheromones. For cats, pheromones are used to mark territorial boundaries, advertise that a cat is ready to mate, or send greetings. Lactating mother cats also produce a blend of “appeasing” pheromones,  that make kittens feel safe and reassured when their mothers are nearby.

Cats release pheromones from glands in their bodies. These glands can be found in…

  • the lips
  • the cheeks
  • the pads of the feet
  • at the base of the tail
  • the area surrounding the teats in females.

Cats communicate by smell -pheromones

When your cat rubs his cheeks against furniture or that corner wall, he deposits pheromones there. Researchers have separated secretions from the sebaceous glands in your cat’s face into 5 pheromone-containing fractions. The “F3 fraction” is thought to be a friendly greeting, marking the area as safe.

Cat Appeasing Pheromone (CAP) is released when the mother cat nurses her kittens. It is a message to the kittens that they are safe and secure – after all, mom is there!

Cats also release pheromones when they scratch, marking territory with another pheromone, FIS or feline interdigital semiochemical. The cat making the scratch marks also leaves behind his own individual scent, giving the next cat who comes along an idea of who left the pheromone message. As time goes on, the pheromones/scents decay. This change in pheromones/scents  notifies the incoming cat when the previous cat was there.

using pheromones to communicate with your cat

It is not surprising that synthetic versions of the F3 fraction of the facial pheromones and CAP have been made with the intention of calming cats and reducing conflict in multi-cat households. These products are available as diffusers or sprays.

Facial Pheromones F3 Fraction

  • Diffuser: place in areas you want your cat to identify as safe and secure, for example, sleeping areas.  You may not need to use the diffusers all the time – after all, your cat or cats are most likely marking these areas themselves. However, the diffuser could give an added boost in times of increased stress, such as home renovation.
  • F3 spray can help with  urine marking. Clean the marked spots with enzyme cleaners (eg. Tide), followed by rubbing alcohol. When dry, spray the spot with one of the F3 sprays.
  • The F3 spray is also useful to discourage scratching. Try spraying the area you DON’T want scratched with the F3 spray and place a scratching post nearby.
  • BSerene spray features the F3 fraction combined with catnip oil to promote calm behavior.

Cat Appeasing Pheromone

  • Diffuser
  • This product can be useful in multi-cat households when introducing a new cat. Place the diffuser in the common areas where all the cats will congregate.
  • You may not need to use this diffuser all the time but it can give a boost during times of stress, for example, when one cat returns from a veterinary visit.
  • The BSerene brand offers a diffuser that contains both F3 and CAP.

A product called Feliscratch contained a synthetic version of FIS. Feliscratch was applied to the scratching post to encourage cats to use it.  This product has recently been pulled off the market due to flagging sales.

No Feliscratch?

  • Make scratchers appealing with treats or catnip
  • If your cat will knead a small fleece blanket, it is possible that this blanket may have FIS deposited on it.
  • Placing the blanket near a new scratching post may attract your cat to the scratcher.

Feliway Optimum – one size fits all?

Feliway Optimum is the result of computer simulation and features a single product designed to address urine spraying, scratching, fear, and inter-cat conflict. It is a proprietary blend of specific pheromones that bind to receptors in the VNO in cats. It comes in a diffuser (Reference 1).

 

How effective are pheromones in communicating messages to cats?

The idea of managing cat behavior using pheromones is appealing. There are no pills to give and you can treat all your cats at once. However, studies aimed at determining whether these products work or not have mixed results (Reference 2).

How receptive an individual cat is to pheromone signals may depend upon her experience (Reference 2).  A free-roaming cat or cat who is a member of a multi-cat household will use pheromone signals more than an indoor cat who lives alone.  A kitten bottle-fed by humans will not be exposed to CAP like kittens nursed by a feline mother.

In my own experience, cats with a feral background respond more strongly to the pheromone products than cats raised in a human household.

You can think of pheromones as those signs in the library asking you to KEEP QUIET or the NO SMOKING signs – there is always someone who is talking or smoking. Compliance is never 100%.

Since cats communicate by smell, synthetic cat pheromones allow us to add some basic messages when we are trying to change a cat’s behavior. Do these products work? The efficacy of these products may depend on the experience of the individual cat.  Consequently, pheromones are best used in conjunction with other behavior modifications.

Introducing a New Cat into the Multi-cat Home

Posted on by felinepurrspective_u3q4o6

Introducing a new cat to an established group of resident cats can be challenging. Most experts recommend a slow, gradual introduction, similar to how wild cat colonies accept new members.

introducing a new cat

Wild cats recognize members of their own colony. Unfamiliar cats will be greeted with aggression if they try to approach and enter the group. This is not to say that non-members don’t join the colony from time to time. If these “outsiders” are persistent in their attempts to join the group, they may be accepted after a gradual process that involves many interactions (Reference 1).

I am in the process of introducing a new cat to my household. The introduction process is still ongoing but here is my progress so far.

Miso is 2 year old male domestic shorthair who had been frequenting the porch where my veterinarian employer leaves food out for the community cats. Miso behaved more like a stray cat and tried to get into the house. So, he was coaxed into a carrier, neutered and had dental treatment at the veterinary clinic where I work.

Miso is friendly toward humans and other cats. Although he is quite a bit younger than my cats, I thought it was worth a try to bring him into my group.

At the time of the introduction, there were 4 cats in my household and two social groups:

  1. Athena, aged 18 years, forms her own social group. She tolerates the other cats but does not snuggle, groom or otherwise interact with them.
  2. Marley, a 17 year old neutered male, 7 year old Gus, and 7 year old Zelda form the second social group. Zelda and Marley will snuggle together particularly when it is cold. Gus and Zelda allogroom; Gus and Zelda also groom Marley.

Getting Ready

 

Introducing a new cat starts with scent exchange. A few weeks before I brought Miso home, I brought home a blanket he slept on and left it in the kitchen area. All four cats carefully smelled it and there was some hissing but that waned over a week.

I made a barricade of closet shelving to close off the downstairs from my resident cats and set up a room downstairs for Miso to stay in with a litter box, scratching posts and food station.

 

Week 1

Miso is calm and confident and asks to go out of his room. He goes out into the catio downstairs. We set up a system of time-sharing the catio, allowing Zelda and Athena to occupy it in the morning while Miso is closed in his room. Miso has the catio in the afternoon.  At night, Miso is closed in his room.

Miso chooses to eat at the top of the stairs next to the barricade. The other cats are fed out of sight in the kitchen.

At the end of the week, I apply a mousse shampoo to Miso and wash his bedding, thinking that he might smell like the vet clinic.  I also put a multi-cat pheromone diffuser downstairs and 4 more on the upstairs floor.

Week 2 – Zelda gets sick

Zelda has diarrhea which I think may be due to the stress of having a new roommate.  The diarrhea  resolves with a few days of probiotics.  

The resident cats frequently hiss while passing Miso at the barricade but they now ignore him and continue on their way. We start to allow Miso upstairs while the other cats are in the catio.

At the end of the week, we allow Miso to have free run of the downstairs and not be closed in his room at night. The barricade is still up.

Week 3 – A Behavior Change for Gus

Miso was trained to harness and leash when at the vet clinic. I officially bring Miso upstairs on a leash and we have our first friendly interaction with the residents – Miso and Gus touch noses and there is no hissing.

Gus greets Miso

Miso is assigned a feeding station (a cat carrier) to eat in and is fed with the other cats. I get a little push back from Gus, who refuses to eat at his feeding station.  I offer him his food on his cat tree which he accepts.

Miso starts doing the evening food puzzle and treat toss with Zelda and Marley. Again, Gus prefers not to participate and does his food puzzles on his cat tree. The barricade is opened during the day near the end of the week.

 

Week 4 – Aggression from Athena

Athena swats Miso and we separate them temporarily, closing Athena in the bedroom. I put a broom near the door way with the water fountain so that I can herd Miso away in case he blocks Athena on her way to water.

There is still plenty of hissing going on but everyone’s body language is neutral. There are still 4 multi-cat pheromone diffusers on the upper floor.  Miso is allowed out in the catio with the other cats.  Everyone keeps their distance.

At the end of the week, Miso is allowed upstairs at night and chooses an empty carrier to sleep in.

Although the cats are sharing common areas now, the process of introducing a new cat is far from over. It will take many more months before all the cats are accustomed to the new resident and the changes in the daily routines.

Introducing a new cat into an established household is stressful for the incoming cat as well as the residents. Even with a gradual introduction, stress-induced illness, changes in routine, and displays of aggression are not uncommon. It is important to monitor the body language of all the cats, accommodate changes in behavior and be ready to separate cats if there is a scuffle.

The Link Between the Environment and Cat Behavior

Posted on by felinepurrspective_u3q4o6
A cat enjoys the scents of a summer night from his window seat.

I remember visiting the zoo as a young child. Back then, the animals’ enclosures were not the large, landscaped areas that you see today. The animals were behind iron bars with a few hides to go into, water, and maybe a tree or two. It was not uncommon to see the tigers or lions pacing repetitively back and forth along the walls of their enclosures or the giraffes continually licking the chain link fences.

These repetitive behaviors are referred to as ARB’s, abnormal repetitive behaviors. In the past few decades, zoos have found that changing captive animals’ environments to allow more natural behaviors reduces ARB’s significantly. Expressing species-specific behaviors allows an animal to control and modify its environment, ensuring survival and reproductive success. Creating a den (safe place) is an example of how an animal controls and modifies its environment (Reference 1).

Environment and cat behavior

Many cats live predominately indoor lives. Our homes are quite different than the territory of a wild cat. The indoor cat often has little opportunity to engage in typical cat behaviors such as hunting and climbing trees. It is not surprising that some domestic cats indulge in ARB’s to reduce the stress of being unable to predict and control their environment.  Overgrooming, where a cat licks or scratches her fur so much that the area becomes inflamed and bald, is one of the more common ARB’s shown by domestic cats.

Of course, a good, solid medical workup may uncover a cause for overgrooming and itchiness – perhaps kitty has a food allergy or skin infection. But it is not uncommon for some of these cases to be “idiopathic”, meaning we don’t know what the cause is.

environment and cat behavior: ARB’s

The wound on this cat’s neck comes from repeated scratching.

A study published in 2018 (Reference 2) investigated the link between the environment and cat behavior. The study followed thirteen cats who had been diagnosed with Idiopathic Ulcerative Dermatitis (IUD).  IUD presents as a crusted, non-healing ulcer on the neck, head or between the shoulders. Medical therapy including surgical excision is rarely successful. The cat scratches at the wound frequently; the wound will heal if the cat cannot scratch it, say if she wears a collar or bandage. Once the collar or bandage is removed, the cat will scratch the area again and the wound reappears. (Reference 2)

 

The research team asked the owners of the 13 cats to institute the following environmental changes:

  • Leave closets open to allow cats to use them as a hideout
  • Free access to food and water (add a fountain if the cat prefers running water)
  • Free access to a garden or balcony/window – a cat door was recommended
  • Provide access to a secure area where each cat can sleep, eat, use the litter box without competing with other cats (some cats were separated from their house mates)
  • Regularly offer new toys to the cat
  • Stop interactions initiated by owner such as carrying the cat, petting the cat. Allow the cat to initiate the interaction.

As soon as environmental changes were set up, the ARB of scratching stopped within 2 days. All cats except one healed – for this cat, the owners were not able make the environmental changes. Oral medication was given to this kitty for two months but the neck wound did not heal. The other twelve cats did not receive medication.  The research team followed these cats for two years and no relapses were noted in that time.

The environmental remedies in this study aimed to give the cat control over her environment by allowing her to exercise typical “cat” behaviors.  These are in line with the AAFP* recommendations for a healthy feline environment (Reference 3):

  • Provide a safe place <> leave closets open to allow the cats to use them as a hideout
  • Provide multiple and separated key environmental resources<>secure area for eating, sleeping and using litter box
  • Provide opportunity for play and predatory behavior <> offering new toys to the cat
  • Provide positive, consistent and predictable human–cat social interaction <> emphasize interactions initiated by the cat
  • Provide an environment that respects the cat’s sense of smell <>  access to a garden/balcony/window exposes the cat to outdoor scents and smells

Although our cats are a domestic species and have lived alongside humans for over 10,000 years, life in our homes sometimes reduces their opportunity to express behaviors typical of their wild relations. The environment and cat behavior are intertwined.  Improving the cat’s environment to encourage species-specific behaviors can reduce a cat’s stress and, in some cases, cure disease.

Note: I don’t agree with free-feeding cats even in such a situation – I think it is better to meal feed and use feeding as a positive interaction with humans. Using food puzzles and tossing kibble for the cat to hunt down allows cats opportunities to engage in foraging and hunting behaviors.

Social Lives of Cats: Family Toms

Posted on by felinepurrspective_u3q4o6

10,000 years ago, the ancestors of our domestic cats decided to take advantage of the abundance of prey near and in human settlements. During this time, the social lives of cats changed from solitary hunters to members of structured, stable groups called colonies. Today’s free-ranging cats, particularly those that live in urban environments, depend on food provided by people, in addition to hunting rodents and raiding human garbage cans.

Social lives of cats: family toms

In urban settings, food is more plentiful and colonies of cats organize themselves near feeding sites. Members of these colonies are friendly with other members but will defend their territory against intruders from other colonies.  (References 1, 2)

Male domestic cats have two mating strategies:(Reference 3)

  • Solitary toms with large home ranges will mate with females from colonies in their home range. These are typically larger cats and they do not form social bonds with the females in the colonies. This is more typical of rural areas where resources are more spread out.
  • In urban settings, males, unrelated to the females, often affiliate themselves with a colony. These “family toms” enjoy the greatest mating success within their particular colony, even if they are small. (References 2,3)

The “family toms” have been known to participate in the care and rearing of the kittens, sharing food with kittens and sometimes disrupting play of juveniles that is getting out of hand with an experienced adult paw.  They also band together with the female cats to drive off marauding tomcats that threaten the kittens. (References 1, 2, 3) Killing of kittens by tomcats is rare in the urban cat colonies (Reference 2).

In contrast, infanticide accounts for 25% of the deaths of lion cubs. When the resident males in the lion pride are displaced by a new “coalition” (group of males associated with a pride), incoming coalition kills the young cubs in the pride, so that the females go into estrus. Thus, the cubs are sired by the new incoming males. ( Reference 4).

Social lives of cats:  my Family toms

I have had two cats in my life that I believe were “family toms”.

Marty

My childhood cat was a male Siamese named Marty. He was an indoor-outdoor cat that somehow did not get neutered until he was 8 years old. He participated in his share of fights with cats and other animals. We always patched him up and let him out again.

I took him with me to college and he lived with me in dorms and apartments. One apartment we lived in had a back door that opened onto an alley. I used to let Marty out during the day. There was a population of cats that frequented the alley. One day, I was walking back from classes and noticed Marty sitting peaceably with these cats.

This social experience might explain the ease with which Marty got along with the kitten one of my roommates brought home and the young cats that I acquired when Marty was about 11 years old. I did not do much of an introduction with these kitties – they seemed to get along immediately. At one point, we lived in a old farm house; the two younger cats would accompany Marty on his expeditions to the neighbor’s house.

Gus

Gus was a free-roaming cat caught in a trap by my veterinarian employer. He is still with me and his story can be read at “Bringing a Wild Cat Indoors“. He lived briefly at the vet clinic where he was always interested in kittens, jumping onto the treatment table when you were giving the kittens vaccines.

Today, Gus watches over the three other cats in my house, looking out for wildlife when we go outdoors (supervised nowadays). One incident that I won’t soon forget involved Gus and Zelda, a female cat in the household. We were walking around our townhome when a terrier dog chased Zelda. Gus took notice and ran the dog off, chasing her away. He then escorted Zelda back to our front door. This level of protectiveness makes me think that perhaps he was a “family tom” in his previous life on the streets.

In the 10,000 years cats have lived with humans, the social lives of cats has changed. Some cats still are solitary hunters but many choose to live in structured, stable social groups. They have been able to change their behavior to take advantage of their environment. The tolerance of kittens and other cats may be one reason the domestic cat has successfully spread across much of the world (with the exception of Antartica).

An additional note…
Attitudes and care of cats has changed in the past 2-3 decades. Many cats live exclusively indoors, enjoying safer and healthier lives. Older and wiser now, I keep my current group of cats primarily indoors with daily supervised outdoor time.

The Social Cats – The Lion Pride and The Cat Colony

Posted on by felinepurrspective_u3q4o6
These two cats have spotted something in the plants by the road. Cats rarely hunt together. Only one cat will get the prize!

The lion pride and the cat colony

I received an interesting comment on a post I wrote recommending feeding house cats separately. The author felt that having cats share a large bowl of food is like sharing a “large kill” and increases “pride unity”.  Lions and cats are the only members of the Felidae (cat family) that live in social groups.  The pride is the social unit of the African lion; the domestic cat will form colonies if there are sufficient resources.  How does the pride compare with the domestic cat colony? 

The lion pride

  • A typical lion pride consists of about 6 related females, their dependent offspring, and a “coalition” of 2-3 unrelated resident males.
  • Most females spend their lives in their mothers’ pride or with their sisters in a new pride.
  • Males may be a bit more mobile, spending a few years in a given pride. They will stay with their coalition throughout their lives. (Reference 1)

the cat colony

  • The core of the cat colony is the queen, her female relatives, and their offspring.
  • There may be a group of “family” males, who spend most of their time with this group of females and develop social bonds with the females.
  • Other males are solitary, with large home ranges that
    overlap the home ranges of several different female groups. These “philandering” males will mate with females from different groups and do not form social bonds with members of the colony. (Reference 2)

the lion pride and the cat colony

Both the lion pride and the cat colony aim to take advantage of resources. Lions and cats need reliable access to food, water and shelter.

Lions

Lions locate in areas where prey is likely to come by. The areas where two rivers intersect are desired locations. Water,  provided by the rivers, and  vegetation, growing near the rivers, attract the lion’s herbivorous prey.

The confluences of the rivers act like a funnel – prey animals get “trapped” in these funnels.  They are attracted by the vegetation but are leery of crossing the rivers, where predators can ambush them.

The lions that band together can protect these valuable territories from other lions and predators.  The pride that controls the territory has reliable access to food and water. (Reference 1)

Cats

Cats form colonies where there are sufficient resources, that is  food, water, and shelter.  The more food there is, the more cats can live in that area.  Large colonies exist where there is lots of food; smaller colonies are located in areas where food is not as readily available.  Where food sources are few and far between, cats adopt a solitary existence. (Reference 2)

The socialization of the domestic cat occurred as humans transitioned from being hunter-gatherers to farmers. The abundance of mice at the grain stores attracted wild cats and provided them with the resources to form colonies.

The lion pride and the cat colony –  Other advantanges

Cubs and kittens have higher survival rates in the pride/colony. The mothers as a group are more successful defending the cubs/kittens. A group of lionesses can successfuly drive off invading male lions, whereas a single lioness does not have a chance. (Reference 1). Likewise, the female cats of the cat colony can band together to challenge invading toms, dogs or coyotes. (Reference 2)

Cooperative Hunting

Lions hunt together when it is needed – for example, when taking down difficult prey such as a Cape Buffalo or zebra. Most of the time, lions hunt singly; their targets are wildebeest or warthogs. Living in a large pride does not mean that you will be well-fed. (Reference 1)

Although groups of 2-4 cats have been observed hunting squirrels and rabbits together, this is not the norm. (Reference 2).  The prey of domestic cats tend to be small and not very calorie dense. An average mouse is thought to have an energy value of about 35 kcal (Reference 3).  It is not practical to share game this small and cats typically hunt alone and dine alone.

More about food…

Male lions typically feed first at a kill, followed by the lionesses and subadult lions. The male lions will aggressively reinforce this feeding hierarchy (Reference 1). 

A study of a cat colony in Rome where humans provided bowls of food found a different feeding-order: kittens were the first to feed, followed by the females and then the males. Typically the male cats are at the top of the social ladder and the kittens at the bottom.  (Reference 4) 

Sharing a large kill appears to reinforce the social hierarchy in lions. In free-ranging cats, we see a social tolerance of kittens by both males and females when feeding in a managed colony.  Although aggressive behavior is rare (<5% of the time) in cat colonies, it is most prevalent around feeding time, but aggression is seldom directed toward kittens.

The Multi-cat Household

Feeding all the cats in the human household at one large dish is unlikely to promote unity.  Instead, competition and conflict over the food will increase as cats try to sort out who eats when and establish a feeding hierarchy.  It is best for our pet cats to dine solo.

The lion pride and the cat colony are matrilineal social groups.  Both groups locate where there is food and water. Both groups result in higher survival rates of cubs and kittens.  The lion pride is an adaptation to life on the savanna whereas the cat colony was an early step in the process of domestication, a social group formed to take advantage of food near human settlements.

Gus is the more experienced hunter and caught the lizard.

Food and Your Cat’s Mental Health

Posted on by felinepurrspective_u3q4o6

Eating is a positive experience for healthy animals. Two neurotransmitters released while eating are dopamine and serotonin. Dopamine is associated with feelings of reward and motivation; serotonin with feelings of happiness and calmness.  Thus, food is one of the ways we can induce a positive emotional state in a healthy cat.

Food and your cat’s mental health

Recent research points to two dopamine events when eating: the first when you actually eat the food and the second, when the food reaches your stomach. (Reference 1). On the other hand, rising serotonin levels act as an appetite suppressant, giving a feeling of satiety. (Reference 2)

The connection between food and your cat’s mental health provides us an opportunity to take advantage of the emotions triggered by dopamine and serotonin when eating.

Foods that calm

There are foods  that incorporate tryptophan, a precursor to serotonin. Royal Canin’s Calm diet  and Hill’s c/d Multicare Stress for cats  contain hydrolyzed milk protein and L-tryptophan to reduce your cat’s fearful behaviors in stressful situations or environments.  The caveat with these foods is that the cat must eat enough of the food to get the appropriate dose of tryptophan.

Cat using food puzzlefood and environmental enrichment

Engaging in foraging behavior can benefit cats with generalized or separation anxiety. (Reference 3)

  • Foraging can provide a cat that is vigilant, tense and easily aroused with an alternative outlet for her energy
  • Cats with separation anxiety will find foraging a rewarding activity that is not related to interacting with the owner.
  • Serotonin release during the foraging cycle promotes calm behavior.

Foraging Method 1 – Multiple Separate Feeding Stations

  • Divide your cat’s daily food ration into portions.
  • Place these in different places around the house.
  • Put some dishes up high or in boxes and closets for variety

Foraging Method 2 – Use of Food Puzzles

  • Cats have to use their paws to get the food
  • Vary in complexity and style

cats with carrier and treatsFood and your cat’s mental health: behavior modification

We can use the positive emotions triggered by eating to guide our cats’ behaviors.  The use of a stream of small food rewards will trigger dopamine release, which in turn gives the cat feelings of reward and motivation.  Food can be a powerful adjunct to some of the interventions used in veterinary behavioral care: (Reference 3)

  • counter conditioning
  • operant conditioning
  • differential reinforcement of alternate behaviors

These methods work best with foods that the individual cat finds particularly palatable and desirable.

counter conditioning and food

Counter conditioning refers to training a different response to a situation.  Consider the cat carrier that takes your cat to the vet.  Many cats have a fearful association with the carrier and the process of going into it.  The goal of counter conditioning here is to teach the cat that good things happen when he’s near the carrier.

We start with getting the cat accustomed to the carrier by just leaving it out in the room.  Once he is comfortable with the carrier left out, we can offer some treats close by the carrier and gradually work up to treats in the carrier.  Over time, the cat will associate good things with the carrier – we have used food (treats) to change the cat’s emotional state when near the carrier.

operant conditioning and food

With operant conditioning, an animal repeats behaviors that have good consequences and avoids ones that are not rewarding.  Say you ask your cat to “sit”. When he sits, you reward him with a treat (food) he likes. He will be more likely to sit next time in anticipation of getting his reward.

differential reinforcement of alternate behaviorS

Here you will be replacing an undesired behavior with one that is more appropriate to the situation.  Say your new kitten attacks and hangs on to your legs as you as come in the door or you have a “door-dashing” cat.  You could train (operant conditioning) your kitten/cat to jump up on a nearby shelf or table on cue for a  food reward when the door is opened.  (The cue can be spoken or you could jingle your keys.) The goal is to replace the attacking/door dashing behavior with sitting on the nearby piece of furniture.

Food makes our cats feel good. Neurotransmitters such as dopamine and serotonin promote positive emotions when eating.  This connection between food and your cat’s mental health provides you with opportunities to influence your cat’s behavior through diet, environment and training.

The Behavior of Feeding – Why Separate Cats When Feeding

Posted on by felinepurrspective_u3q4o6
Gus eyes Athena’s dinner and prepares to move in.

Solitary hunters, cats will eat or cache their prey after a successful hunt. Mother cats will bring prey back to their kittens to teach them how to hunt and what to eat but cats typically DO NOT SHARE their prey. They will growl when eating to warn other cats off.

In photos taken on the “cat islands” of Japan (called neko shima), cats line up at dishes of food put out by the island residents. There are 11 islands in Japan that have more cats than people on them. There are not enough mice for the cats to eat so residents of the islands provide food for the cats.  Feeding times appear to go smoothly on the cat islands with the occasional spat between cats. The island residents do put out food in more than one location so a cat can always move to another feeding station if he gets into a fight over food. Contrast this with our picture of a wild cat, a solitary hunter, munching his mouse in solitude.  

Our indoor cats don’t have the option of leaving if they are the target of food aggression.  Although cats may appear to get along eating next to another cat or out of the same bowl, cat behavior experts recommend that we separate cats when feeding, preferably out of sight of other cats. (Reference 1)

Why separate cats when feeding?

  • Cats with more dominant personalities will nose smaller, more timid cats out of the food bowl.
  • Victim cats may gorge and eat their food quickly, leading to “scarf and barf”.
  • Victim cats may start to lose weight.
  • House-soiling issues can start if the “bully” decides the game should extend to resources other than the food bowl.

These behaviors can be subtle. The “thief “at first just sits quietly near the “target” cat and stares at her. The target may stop eating. There may be some fisticuffs as the target tries to keep eating.  Eventually the thief just noses the target out of  the bowl, and the target cat leaves.

Strategies to separate cats when feeding

Assign each cat his own food station out of sight of the other cats. If you are meal feeding, you can fill each station with a cat’s portion and call each cat to his station as you place them around the house. Collect the feeders in 15-30 minutes as the cats finish their meals.  If you like, you can offer the meals in food puzzles, one per cat.

Locations of feeding stations

You may be able to take advantage of your cat’s preferences when deciding where to locate her feeding station. Some cats like to be up high and can be fed on their cat tree or tops of shelving units.

Closets can also make good feeding stations. Cats who like to be up high can eat on the top shelf and may just need a step ladder, storage cubes that form a ladder, or a single pole cat tree to get up there. If you just need to keep the family dog out, a gadget called a “Door Buddy” can work.

Baby gates can be used to block off doors to closets or rooms to separate cats. Although an agile, determined cat can easily scale a baby gate, this is usually pretty difficult for a dog.

feeding stations

Microchip Feeders

If you are dealing with cats on different diets or cats that eat slowly or “graze”, microchip feeders such as the SureFeed Microchip Pet Feeder are worth the cost. These feeders will only open for the cat or cats they are programmed for.

Enclosures for Feeding

A “Meow Space” is a deluxe feeding enclosure. It is ventilated and has a locking pet door which can be accessed by microchip or collar tag.  Like a microchip feeder, the “Meow Space” will only open for the cat or cats it is programmed for.

A plastic pet carrier can make a great “kitty diner”. Each cat can eat in his own carrier. If one cat finishes before another, the gate can be closed until the slower eater is done. This also helps your cat become more comfortable with his/her carrier.

Tip: Make a carrier cover that will “camouflage” the carrier, matching your color scheme and decor.

not enough room to separate cats when feeding?

Consider feeding social groups together.  Cats who belong to the same social group prefer to spend time with each other and are often willing to share resources such as food and litter boxes.

How do you know if cats are affiliated? The following behaviors can help you identify the social groups in your home.

  • Sleeping the same room
  • Allogrooming (grooming each other)
  • Sleeping touching each other
  • Touching noses

Note who does what and with whom, then diagram the social groups in your house. You may be able to feed cats in a social group in the same area. It is still recommended for each cat to have a separate bowl, be spaced apart, and to meal feed the kitties.

Separating your cat from other animals while eating allows your cat to feed in the same way as a wild cat. Feeding alone helps avoid behaviors like gorging and vomiting which can affect a cat’s physical and mental health.  Although it can be a challenge to separate cats when feeding, attention to each cat’s preferences and identifying the social groups in your home can help you develop a feeding strategy.

The Behavior of Feeding – Why Meal Feed Your Cat

Posted on by felinepurrspective_u3q4o6
Leaving tasty kibble out all day is like a having a bowl of potato chips on the counter.

A wild cat’s day begins in the late afternoon. He is an opportunistic feeder, a generalist, who will eat anything from bugs to bunny rabbits. He may snack on a lizard, sunning in the late afternoon sun. As the shadows grow longer, he will go on the prowl, looking for the small rodents that make up most of his diet. If he is lucky enough to catch something, he will retire and dine al fresco, alone. He will then doze or nap a bit while his meal digests. If he is part of a cat colony, he may groom or play with the kittens, while their mothers hunt.

In a few hours, he’s off to hunt again and will keep on prowling, looking for prey. He is not above scavenging a meal from other animals’ leftovers or from human garbage. His stomach is small and he will eat a 6-10 meals as he hunts through the night. When the sun starts to rise, he will turn in for the day, sleeping, grooming and sunning.

The behavior of feeding – why meal feed your cat

Our indoor cats have chosen a different lifestyle.  They depend on us, their human caretakers, for their food. They may be fed in one location with other cats, once or twice a day or be free fed from a large bowl of kibble available 24/7 (Reference 1).

The Problem with The big bowl and free feeding

Imagine a big bowl of potato chips or crisps left on the counter.  You pick one or two as you go by.  It is very easy to continue snacking and before you know it, that bowl is getting empty.  In the same way, it is easy for a cat to eat too much of  palatable and caloric kibbles left out, nibbling a little at a time.

Free feeding with more than one cat in the home

  • Cats with more dominant personalities will nose smaller, more timid cats out of the food bowl.
  • Victim cats may gorge and eat their food quickly, leading to “scarf and barf”.
  • Victim cats may start to lose weight.
  • House-soiling issues can start if the “bully” decides the game should extend to resources other than the food bowl.

The behavior of feeding – what can we learn from wild cats?

  • Cats have evolved to eat multiple, small, low calorie meals every day.
  • Cats prefer to eat alone – without other cats around.
  • Cats spend most of their waking hours hunting and foraging for food.

the take-away for indoor cats

  • Meal feeding reflects the way cats naturally eat.
  • Cats need to be fed separately from other pets (cats, dogs) in the house.
  • Cats need to engage in hunting/foraging behavior.

Choosing to meal feed your cat

It does not need to take a lot of time and effort to meal feed your cat. Divide your cat’s daily allotment of food into 4-5 portions. Your cat will be happier – he will have more to look forward to and his food will be fresher, as smaller portions will be put out frequently instead of topping up the bowl.  Check out the Meal Planner below – mix and match the meals that work for you!

Canned foods lend themselves to meal feeding.

Meal #1

If your cat enjoys wet food, offer a wet meal when you are home to pick up the dishes.  Choose an amount your cat can finish in 15 minutes or so.

Meal #2

Dry food can be placed in bowls or feeders around the house. You can change the locations of these daily if you like to keep your cat on his game.  Timed feeders can meter out the food while you are away.

Meal #5

Food puzzles offer foraging opportunities to cats. But be forewarned: most cats are lazy – they will choose food that they do not have to do anything for.  You have to meal feed for this to work – otherwise, the cat will just go and snack out of his bowl.

More About Food Puzzles

Most likely, you will need to “train” your cat to use a food puzzle. Once your cat learns one, she will pick up on others more quickly.  When your cat knows how to do several of these puzzles, you can rotate them to keep her interest. For more about the psychology of food puzzles and training your cat to use one, see  “Cats Eating From a Food Puzzle: Contrafreeloading?“

Choosing to meal feed your cat allows him to engage in more natural feeding behaviors.  It will be easier for you to regulate his intake which is better for his health and longevity.  With a little bit of creativity and using the Meal Planner, you should be able to meal feed your cat, whether she is a dry food addict or eats a combination of wet and dry foods.

Tips for Managing The Cat With Pica

Posted on by felinepurrspective_u3q4o6

a cat chewing on plasticHave you had or do you have a cat who would eat anything – hair ties, ribbons, plastic – in addition to food? Have you experienced the anxiety waiting for your cat to pass whatever object you think he ate? It is not unheard of for cats to eat, chew or suck on non-food items. This behavior is called pica.  How do you manage the cat with pica?

The Bristol Cat Study (Animals 2021, 11(4), 1101; https://doi.org/10.3390/ani11041101) followed a group of cats for a little over 3 years.  To participate in the study, the owners had to own a kitten or kittens, 8-16 weeks old at the time of registration.

These owners were asked whether or not their cats chewed (with or without ingesting) one or more of the following items: 1) woolen fabrics 2) other fabrics 3) plastics 4) other materials. These questions were repeated at 2-4 months, 6.5-7 months, 12.5-13 months, and finally at 18.5-19 months.  About 25% of 2203 cats were reported to exhibit some pica behavior.

Findings

  • plastics were the most commonly targeted material
  • pica was most commonly reported at 6.5-7 months of age
  • about half of the cats reported to have pica at 6 months did not show pica at 18-19 months of age
  • cats who moved to a new house when they were around year old were more likely to have pica

 

Managing the cat with pica

Pica can result in GI injury, poisoning, or electric shock. The goal of managing pica is to prevent injury to the cat.

Step one: Identify the material being targeted

Yarn? Thread? Hair Ties?

  • yarn can wrap around the tongue
  • thread may have a sharp needle attached
  • hair ties

Poisons?

  • Household chemicals: cleaners, antifreeze, insecticides, plant sprays
  • House Plants: can be toxic – lilies in particular can cause kidney damage even in small amounts

Other?

  • Filmy plastics and things like “fabric softener sheets”
  • Chewing/biting electrical cords
  • Kneading and sucking on blankets
  • Chewing or sucking on toys

Step two: Keep targeted items out of reach of the cat with pica

  • keep blankets and other fabrics in closets your cat can’t get into
  • put hair ties and elastics away
  • replace toys your cat may be eating with ones that he can’t eat
  • supervise play times and access to toys
  • cover electrical cords with plastic covers that cats can’t bite through
  • unplug unused appliances
  • discard or hang houseplants
  • store household chemicals in a secure closet

Step three: Provide the cat with pica an alternative behavior

We would like to provide Kitty with an outlet for her oral activities and provide something safe for her to interact with.

Cat using food puzzleKeeping kitty busy


Try “free feeding” your cat with pica if possible. If “free-feeding” is not an option, frequent small meals will work. Food puzzles offer a natural cat behavior (foraging) as well as a snack. For some ideas, visit foodpuzzlesforcats.com.

Licking – a soothing behavior for cats


Slow-feeding mats are textured silicone mats that you spread canned food on. The cat licks the food off much like a wild cat may lick meat off a bone. Licking appears to be calming and soothing to cats. Some cats may like licking toys or balls made from compressed catnip.

Chewing

There are silicone toys that can be filled with catnip or silver vine (see the PetZone Boredom Buster dental chew toy). There is also a gum stimulator on the Catit Wellness Center that is designed to be chewed and sucked on. If you try these, be sure to monitor the wear on them and be around to supervise your kitty with these.

Cat Grass


Cats are attracted to grass and like to chew on it. There is the grass sold at pet stores and seeds you can plant. Some varieties of ornamental grasses are non-toxic to cats. Make sure to check the ASPCA site to make sure that the plants you choose are safe.

Step four: reducing stress in the cat with pica

Stress can stimulate an increase in pica behaviors, especially as cats grow out of the kitten stage. Identify and reduce stress whenever possible.

Social stress: 

  • How does the cat with pica get along with other pets in the household?
  • Do neighborhood cats come to the windows?
  • Are interactions with humans
 predictable?

Environmental stress:

Managing the cat with pica can be challenging.  Although the Bristol Cat Study indicated that half the cats who had been reported with pica at 6 months were no longer chewing/ingesting things at 18 months, it is wise to monitor your cat for such behavior, even if it seems to have gone away. Providing cats with safe opportunities to lick and chew is key to having a happy and healthy cat.

Your veterinary team is an important resource if you suspect your cat has pica. GI distress, oral pain and neurological issues can sometimes exacerbate pica and are best treated.

How Cats Get Along with Other Species

Posted on by felinepurrspective_u3q4o6

A cat and dog relax togetherIn this post, we look at how cats get along with other species – are their behaviors affiliative or is there conflict?

How cats get along with other species

How Cats Get Along with People: Signs of Affiliation

In an interview with Terry Gross of  the NPR show, “Fresh Air”, the well-known anthrozoologist, John Bradshaw, noted that cats view their owners as cats, specifically cats they are affiliated or friendly with.  Cats greet us as they would an affiliated cat, rubbing up against us, touching their noses to our hands, licking our hands and faces, snuggling next to us in bed at night.

Rubbing our legs is an affiliative behavior.Cats use the same friendly behaviors when interacting with people as they do with other cats.

  • nearness
  • rubbing up a person’s legs (allorubbing)
  • bunting against our hands (nose touching)
  • licking hands (allogrooming)
  • approaching with tail up

How Cats Get along with people: Signs of Conflict

Cats show similar conflict behaviors when interacting with humans that they would use with other cats.

  • staring
  • stalking and pouncing
  • running away
  • biting, swatting and swiping
  • arched back and hair standing on end

Young cats in particular can be guilty of stalking and pouncing on owners as they round a corner in the house. Some of these behaviors can be the result of playing with the cat inappropriately or redirected aggression, where the cat associates the owner with a fearful experience.

A petting session sometimes comes to an end when the cat bites or swats the person petting him, then jumps down and runs away. It is important to add to the list above some “pre-conflict” behaviors that we must watch for:

  • flattened ears
  • fur on the cat’s back ripples
  • the cat turns to face you with a stare

How Cats Get along with Children

Cats showed no preference to gender or age when meeting volunteers in a shelter for the first time. The volunteers did not interact with the cats but instead read an age-appropriate book. [Turner, The Mechanics of Social Interactions Between Cats and Their Owners]

After 5 minutes, the volunteers were allowed to interact as they pleased with the cats. The cats reacted strongly to the differences in behavior between men, women and children. Women and girls tended to move onto the floor with the cat and speak quietly; men remained seated, and boys approached the cats immediately, causing them to run away. [See below Turner].

Children, being more active, and less attentive to the body language of cats, tend to elicit more conflict behaviors from cats then adults. Children playing with cats must be supervised by adults as young children, in an excess of enthusiasm, may hit the cat with a toy or chase them.

A cat’s impulse is to flee when chased by a child but if cornered, he may bite or scratch. It is important to allow cats avenues to escape the attention of boisterous youngsters – high cat trees or closets with latches that allow the cat access but not the child.

How Cats Get Along: Cats and Dogs

Although cartoons and films may show cats and dogs as mortal enemies, many co-exist peacefully in human homes.

A recent survey based study by Thomsen et al. (cited below), indicated that the success of the relationship depends on the age of the cat (preferably around 6 months) when introduced to the dog. Ideally, good experiences with friendly, well-behaved dogs during the cat’s “sensitive” period will predispose the cat to forming relationships with dogs. Slow, gradual introductions between cat and dog (similar to Introducing Cats) have the best chance at success

Just like with humans, cats tend to show the same behaviors to dogs they are friendly with that they would show to other cats.

  • sleep in the same room as the dog, sometimes touching
  • rub against the dog when greeting
  • approach with tail up

Although a dog may be affiliated with the cat in his house, this does not mean he will not chase or bark at a strange cat. A cat who has been raised with dogs may still turn and flee from dogs he does not know. Affiliation exists between individual animals, not a whole species.

Dogs also have a set of affiliative behaviors. The hallmarks of a well-socialized dog include:

  • relaxed body
  • rapid tail wag
  • no staring
  • indirect approach, looking and sniffing at the ground

Canine conflict behaviors include:

  • backing away or trying to escape
  • submissive behaviors: flattened ears, tail tucked, looking away
  • staring, growling, snapping, erect posture
  • tail held vertically or arched over the back

Another survey-based study (Menchetti et al. cited below) compared owners’ perceptions of how dogs and cats living in their homes get along. Owners felt that:

  • Dogs are more social than cats towards strange animals and humans
  • Dogs are more playful than cats with their owners
  • More dogs lick the cat than vice versa
  • More cats ignore the dog than vice versa
  • Most dogs and cats in the same household will sleep together and play together at least occasionally
  • Although cats and dogs have different body languages, they still manage to understand each other

A Tale of Tails

Both cats and dogs use their tails to communicate.

 CatsDogs
Friendly GestureTail upTail wagging
ConflictTail twitchingTail up

Somehow, cat-dog pairs translate each other’s language. The cat approaches the dog for a nose-to-nose greeting with tail up and lies down beside him. The dog recognizes the cat’s behaviors as positive signals and he wags his tail.

When the dog approaches the cat with the tail up, the cat recognizes the conflict/aggressive signal, arches his back, twitches his tail and backs slowly away.

Cats will use the same visual signals that they use with other cats when interacting with other species, such as humans and dogs. It is important that we, as pet guardians, know and understand the affiliative and conflict behaviors of each species residing in our homes to prevent altercations and promote peaceful coexistence.
