Allergic to Cats? Strategies to Keep Your Cat With You

Posted on October 30, 2022 by felinepurrspective_u3q4o6

Some folks view Sphynx cats as Hypoallergenic cats.

Did you know that 10-20% of the world’s human population is allergic to cats (1)? Symptoms range from itchy eyes, stuffy nose, and sneezing to skin rashes and hives. More serious reactions may include asthma and difficulty breathing. Over the counter medications can relieve some but not all of the discomfort and these medications are not without side-effects. Are there other ways to manage these allergies?

This post is an update of one published about 1 year ago. I felt it was worthwhile to bring people’s attention to the subject again.

Allergies and the cat-human bond

Allergies can come between you and your cat. You are miserable around your cat when your allergies flare up.

You start to avoid your cat.
He is outlawed from the bedroom.
His needs, particularly consistent human interaction and interactive play, are not being met.
Not only are you feeling bad, but your cat can become stressed.
Stress can lead to medical problems such as diarrhea, and resurgence of viruses such as herpes.
It is not unheard of for people allergic to cats to re-home their beloved pets.

The Culprit

A protein called Fel d1 is the primary allergen in cats.
Fel d1 causes 95% of the allergy responses in adults allergic to cats.
Fel d1 is produced in the cat’s salivary and sebaceous glands.
Your cat spreads Fel d1 through his fur as he grooms.
As he sheds fur and skin (dander), Fel d1 is distributed throughout your home.
Breathing in dander or having contact with it can trigger an allergic reaction.

Fel d1 is light, easily airborne and can be found just about everywhere, even in pet-free homes and institutions such as schools. Usually these levels are low and do not impact people in general. Fel d1 may be spread by the clothing of people who keep cats (1).

Managing Cat Allergies

REDUCING FEL D1 IN YOUR HOME

Here are some things you can do:

Fur tends to “stick” more to fabrics – vacuum upholstery and carpets frequently.
Consider switching out carpet for hardwood or vinyl floors.
Use covers that you can launder on sofas and upholstered chairs.
HEPA air filters and HEPA vacuum filters can also help.
Clean regularly and frequently.

REDUCING FEL D1 ON YOUR CAT

Not all cats shed Fel D-1 at the same rate. Even an individual cat does not always shed the same amount of this protein at any given time – instead it varies throughout the year.

NO HYPOALLERGENIC CATS

Some folks think that certain breeds of cat don’t produce much Fel d1. These cats typically do not shed much. It is thought that the reduction in the amount of hair reduces the amount of Fel d1 in the environment.

However, Fel d1 is mainly produced in the sebaceous glands in the skin and in the cat’s saliva, not in the hair. So even a “bald” Sphynx will still groom and spread dander that has sebaceous secretions containing Fel d1 (1)

BATHING YOUR CAT

Bathing your cat does reduce the amount of Fel d1 but levels return to pre-bath amounts within 2 days (2). Of course, many cats do not tolerate being bathed. There is a mousse shampoo designed to reduce Fel d1 – this may be better accepted by cats than a traditional soap and water bath.

“NEUTRALIZING” FEL D1

Fel d1 like most allergens, has a chemical “key” that locks into receptors on cells in our bodies. What if you “lock up” Fel d1 before it gets to us?

Chickens produce antibodies against environmental antigens that they can transfer into their eggs and give their chicks immunity against these antigens. Researchers at Nestle-Purina developed an “anti-Fel d1” antibody by exposing hens to Fel d1. This antibody is incorporated into the dry cat food, Purina “Live Clear” .

How it works:

A cat eats food containing eggs from these hens.
The “anti-Fel d1” antibody “locks up” active Fel d1 in the cat’s saliva.
When the cat grooms himself, he spreads the “locked up” or neutralized Fel d1 on his fur. He probably also spreads some of the “anti-Fel d1” antibody, which further neutralizes some of the allergen produced by the sebaceous glands of the skin.
Studies show that active Fel d1 is reduced by an average of 47% after 3 weeks of feeding.

Although not a perfect solution, feeding this diet may just help reduce the allergen burden enough to make you, and consequently your cat, more comfortable.

WHAT DOES THE FUTURE HOLD FOR THOSE OF US ALLERGIC TO CATS?

HUMAN-DIRECTED THERAPIES

“Anti–Fel d 1” monoclonal antibodies are being developed that can be given by injection under the skin to humans allergic to cats. Preliminary studies showed a 60% reduction in symptoms in half of the patients. (2)

CAT-DIRECTED THERAPIES

Saiba Animal Health is developing a vaccine that triggers an immune response in the cat’s own body to develop antibodies to Fel d1. “Hypo-Cat” showed a 50% reduction in Fel d 1 levels detected in cat tear extracts, decreasing symptoms in nine allergic patients by about 30%. (2)

Other research is using CRISPR (gene-editing) technology to delete the genes responsible for producing Fel d1, with the aim of producing a truly hypo-allergenic cat. (2)

closing thoughts

The function of Fel d1 is unknown – this protein is only found in the cat family. Some experts feel it is a pheromone (3)– a chemical used to communicate between members of the same species.

This raises some questions:

What message does Fel d1 carry between cats?

Is it ethical to modify the feline genome to breed cats that don’t produce Fel d1?

How will we be changing our cats when we do this?

Strategies for Counter-Surfing Cats

Posted on October 23, 2022October 23, 2022 by felinepurrspective_u3q4o6

After adopting a feral cat 3 years ago, I am still struggling with cats on the counter. Gus spent most of his wild life dumpster diving, and hunting mice and bugs for food. He certainly would have availed himself of any food a good samaritan left out for the community cats. Understandably, the kitchen counter is a cornucopia of food as far as he is concerned.

Counter-surfing cats – Why do they do it?

Cats are looking for food.
Cats are curious and keen observers of other species and their activities.
Cats like high places and may feel safer on the counter, out of reach of the family dog and children.

Strategies for Counter-Surfing Cats

The Foodie Cat

Have food on the counters only when you are preparing it.
If you need to leave during food prep, be sure and secure the food in a cabinet or unused oven.
Train your cat to a mat.

The Curious Cat

Offer your cat a place where she can monitor counter activities.
Train her to stay at that place while you are at the counter.

The Trapped Cat

Offer your cat a place where he can get away from the children and/or dog.
If he still prefers the counter, train him to stay in the place you offered.

Mat Training

Mat (aka station) training is popular with dog trainers. Ideally, when you tell your dog to go to the mat, he goes there and waits on the mat until you tell him he can leave. Mat training can be very handy because the “place” the dog must go to can move around – it is wherever the mat is.

Cats can also be mat trained. Here is how it works.

Choose a mat for your cat to sit on.

Encourage the cat to go to the mat by, say, throwing a treat on it.

Reward the cat once she interacts with the mat.

If she gets off the mat before you tell her to, encourage her to return to the mat.

“Shape” the behavior by having her stay on the mat for increasingly longer periods of time.

Establish a cue to let her know she can leave the mat.

Counter Control – Other Aids

Aversives – things cats don’t like

A non-toxic citrus spray on the counter (cats don’t like citrus)
An upside-down carpet runner (with the “spikes” facing up)

Punishment

Water guns are a traditional solution to deter counter-surfing cats…for these to really work you must spray the cat as she is jumping on the counter.
Motion-activated spray systems (SSSCAT) may discourage counter-surfing cats as long as the device works…but these devices can startle and frighten some cats.
See “How Does Clicker Training Your Cat Work?”

Counter-Surfing Cats – a Hard Case

Having been a feral cat, food is Gus’s major priority in life. He inevitably jumps on the counter if there is any suggestion of food preparation. He is always willing to get down from the counter when I point my finger to the floor but he returns to the countertop in a few minutes. He is undeterred by water guns, citrus sprays, and upside down carpet runners.

Gus easily mastered the idea of station training – sitting and staying on the mat is not problem until you start food preparation. He is fine as long as the treats keep coming. However, if I fall behind dispensing treats (when breading cutlets or some other involved culinary task), he returns to the counter again. I feel he cannot “dial back” his emotions enough to recall his training.

Solutions

If the cooking is so complicated that I can’t pay attention to Gus, I will put him in his “safe place” (the master bedroom) with his resources and some food.
If things are not too hectic, I will give him a lickimat with some baby food on it. This seems to keep him happy and contented for 15- 20 minutes.

Counter-surfing cats are often looking for food, a good place to monitor activity in the house, or a way to escape the family dog or a busy toddler. Decide where you want your cat to be and see if you can train her to go to a mat in this place. If all else fails, put your cat in her “safe place” while you fix meals, work on projects, or entertain guests.

Cats and Scratching 3: First Aid for Unwanted Scratching

Posted on October 2, 2022 by felinepurrspective_u3q4o6

Cat scratching near stairs — A scratcher redirects this cat from scratching the stairs.

Sometimes, even after you have invested in several scratching posts, your cat will scratch somewhere you don’t want her to. What is going on?

Earlier we learned that cats scratch to maintain their claws, to stretch and to communicate with other cats by leaving a scent mark. Scratchers need to be “deployed” where they will best satisfy these needs.

How to deal with unwanted scratching

Redirect the cat to scratch on an “appropriate” surface.
Respond to any scent messages.
Use “aversives” to discourage “unwanted scratching”.
Offer alternate marking options for your cat.
Trim nails to minimize damage.

Redirecting unwanted scratching

This basically means we place a scratcher close to or at the place your cat is scratching. We will “sweeten” the deal by applying an “attractant” to the scratcher – catnip, silvervine, honeysuckle. We can also add some treats and reward kitty for using this scratching alternative.

Say your cat starts scratching your sofa. You notice a big orange cat outside the picture window where your sofa sits. Some things you may consider:

Put a cat tree over by the window to give your cat a vantage point and a place to mark by scratching.
You may want to move the sofa away from the window.
Reduce visual contact with the intruder – cling film on windows or prevent cats from coming into the yard to the window (fence rollers, motion-activated sprinkler)

Reply to any scent messages

You just bought a new sofa. Your cat may feel that the new sofa needs to be “broken in”. A little scratching leaves a purrsonalized “greeting”. And then once Kitty scratches there, of course, he better “top off” that message regularly so that it is up-to-date.

Start with providing an acceptable scratching surface at or near the area of “unwanted” scratching. Use attractants as needed for your cat.

We need to let your cat know that this sofa is “safe” and “already marked”. We have a few options to achieve this.

Use a synthetic pheromone spray such as “Feliway” Classic or Comfort Zone Calming. These are synthetic versions of the secretions cats deposit by rubbing their cheeks against things. To avoid staining your sofa, we can spray a throw or blanket that we drape over the sofa. Initially, you will need to spray this daily.
Or – relocate the sofa close to an electrical outlet and use the “Feliway” Optimum diffuser. This novel blend of feline pheromones has been shown to reduce feline stress and unwanted scratching.
Or – you may use the blanket your cat sleeps on and drape that over the sofa. You will want to have a second blanket that he sleeps on so that you can swap them out daily at first.

“Aversives” – things most cats don’t like

Upside-down carpet runner: the spikes face up and are not comfortable to walk on! Place the upside-down runner where your cat may stand to scratch, say under the sofa that is getting scratched. Place a scratching post nearby on a “comfortable” surface.
Double-sided sticky tape (Sticky Paws is one brand). This works well on fabric and carpeted surfaces. It is applied to where your cat is scratching.
Aluminum foil can be wrapped around the furniture or placed on the floor.
Carpet runner or office chair mats (right-side up) may work if your cat is scratching at the carpets around doorways. There are also anti-scratch mats made for this purpose.
PLEASE avoid using things like garlic and essential oils to discourage scratching – these can be toxic to cats.

A Word about Punishment:

Spray bottles, SSScat spray deterrents, shock mats – these may seem effective but all run the risk of making your cat fearful and anxious. You are punishing the cat for an instinctual behavior – she is not doing anything wrong; she is just using a surface you don’t want her to. It would be better to restrict her from the area than use punishment.

Alternative Marking Options for your Cat

Cats scent mark using glands in their cheeks, lips and base of the tail. We think that these pheromones give cats a message of safety and security – this place is “marked”. There are self-grooming arches that cats can brush under and grooming combs that attach to wall corners, table legs and cabinet corners. Your cat can mark these objects by rubbing her face, head and base of her tail in these areas.

In multi-cat homes, cats may scratch to establish their right-of-ways inside the home. Strategic placement of a few self-grooming stations may help reduce scratching by providing another way of marking. ( see T. DePorter and A. Elzerman, Common Feline Problem Behaviors: Destructive Scratching Journal of Feline Medicine and Surgery (2019) 21, 235–243)

Minimize damage with nail trims

Train your cat to have her claws trimmed using positive reinforcement. You may need to trim claws every 4-6 weeks. Trimmed claws should not damage surfaces as much as untrimmed claws.

cats just want to have fun!

Cats will sometimes scratch to work out the “zoomies” or to get your attention. Scratching carpeted stairs often falls into this category!

If your cat enjoys scooting along stair risers:

Sisal pole at botton of stairs — Sisal pole at the bottom of stairs

Consider blocking the stairway with a tall pet gate or DIY barricade.
Turn a replacement sisal post on its side and put some ends on it heavy enough to keep it in place but low enough to give the “stair scratching experience”. Push it up against that bottom step, and let the fun begin. Don’t forget the catnip and treats!

Claws come with your cat. He will scratch to maintain his claws, stretch, and leave scent messages. To deal with unwanted scratching:

direct him to an appropriate scratcher using catnip/silvervine and treats
use pheromones
use aversives as needed
provide other ways to scent mark
trim his claws regularly.

Avoid punishment – instead be a cat whisperer and try to communicate with your cat.

Cats and Scratching Part 2: The Purrfect Scratching Post

Posted on September 25, 2022 by felinepurrspective_u3q4o6

This kitty prefers her cardboard scratcher to a large cat tree.

There are scratching posts, there are cat trees with sisal rope attached to the supports, there are cardboard scratchers of all shapes and sizes – which scratching post should you choose for your cat?

Unfortunately, there is no easy answer to this question.

cats and scratching: the “purrfect” scratching post

A recent study published in Applied Animal Behavior Science video recorded 36 adult cats to identify the cats’ scratcher preferences.

Adult neutered male cats preferred a standing scratching post over an S-shaped one – spayed females did not show a strong preference here.
Scratchers with sisal rope and cardboard were used more often than those covered with sofa fabric.
Catnip and silver vine treated scratchers were favored over those treated with artificial pheromones.

In this study, the catnip, silver vine and artificial pheromones were hung in a sock on the scratcher. Would it make a difference if the artificial pheromone was applied directly to the scratcher, mimicking how a cat would deposit these scents?

Still another study (2019) recruited 8 week old kittens from a shelter population. The kittens:

Preferred cardboard S-shaped scratchers over posts with rope.
Adding catnip to the scratchers did not attract the kittens (this is not surprising – the catnip response does not show up in kittens until they are 3-6 months old.)

A third study, this one an internet-based survey of 4015 cats in 39 countries, found:

Rope was more frequently scratched than cardboard or carpet.
Cats scratched more often when the post was a simple upright type or a cat tree with two or more levels, at least 3 ft high.
Unwanted scratching decreased as the different types/styles of posts increased in the home.

This survey concluded that the “Ideal Scratching Post” would

have sisal rope
have vertical scratching surfaces
be more than 3 feet tall
have two or more levels
have a base of 1-3 feet

So, should you run out and purchase one of those, large multi-level cat trees? Will this take care of all your scratching issues? Let’s take a look at four different cat scratching stations in a 4 cat household.

Station 1: Multi-level Cat Tree with Sisal posts for scratching

This tall cat tree is located in the interior of the house away from doors and windows. The younger cats (6 years), Zelda and Gus, use this tower to snooze on the upper levels or to get to the tops of the kitchen cabinets. Although it does meet the recommendations for the ideal scratcher, the cats don’t scratch on this tree all that much.

Station 2: Single Post scratcher and cardboard scratcher

This very tall post (it is 41″) with sisal fabric is at the front door. It is popular with everyone, from the 17 lb Coon cat to the small senior at 8 lb. All four cats scratch before going out for a walk or when they sit to look out the window in the front door. The horizontal cardboard scratchers at the front door also see consistent use. The cats tend to use these with all 4 feet on the scratcher.

Station 3: Large cat bed with sisal scratcher

The sisal-covered base of this extra-large cat bed is tall enough for the large Maine Coon to scratch. This cat bed is located in the bedroom. It was purchased for the Maine Coon cat but has been taken over by 8 lb Athena, who sleeps in this bed or in her heated bed at the base of the scratcher. When she gets out of bed, she stretches and scratches on this scratcher. This is used infrequently by the other three cats.

Station #4: By a litter box

This is a single pole covered with sisal rope. This post sees a lot of use by all four cats.

In this household, location appears to affect how much a scratcher is used.

Cats scratch to maintain their claws, to stretch and to scent mark. Most scratchers are probably used for all three purposes. So, which scratcher should you choose? Experts recommend starting with the multi-level cat tree with sisal rope supports. However, cats are individuals and, if your cat does not take to this type of scratcher, offer different types and styles.

The Take Away

Have more than one scratching station.
Have a variety of scratchers.
Move them around and see where they get used the most.
Watch your cat’s habits – try to pick a scratcher that you feel will be appropriate for your cat’s age, size, and level of activity.

The next post will look at first aid for unwanted scratching – what you can do when your cat scratches where you don’t want her to.

What We Know About Cats and Scratching Part 1

Posted on September 18, 2022September 18, 2022 by felinepurrspective_u3q4o6

cat scratching tree — Gus scratches a tree on his morning walk.

One of the topics I touch on in the first session of kitten kindergarten is providing kittens with a cat-friendly home, following the environmental requirements suggested by the International Society of Feline Medicine.

Five “Pillars” hold up a cat-friendly home. They are:

multiple, separated resources (litter boxes, food, water, places to sleep)
opportunity for predatory play – those toy mice are good for hunting practice!
positive, consistent, and predictable human-cat interactions
a place where the cat feels safe
a place that respects the cat’s keen sense of smell

All cats scratch – it is normal for cats to scratch. Where does scratching fit into the cat-friendly home?

cats and scratching:why

To maintain their claws: Cats use their claws to hold mice and other prey; they also use their claws to defend themselves. Sharp claws work better for hunting and defense, so cats will often scratch on trees, logs or fence posts when outdoors to shed old claws and expose the new, sharp talons underneath.

To stretch: A scratching post provides a great place to stretch after a nap.

To communicate with other cats: As a cat scratches, glands in her feet release a pheromone. This chemical leaves a scent behind that lets other cats know who left the scratch marks and when. The scent accumulates over time and provides a reference point in the scent map the cat has of her home. She also finds her own scent and the scent of the cats from her social group comforting. We humans also find some scents soothing, like the smell of apple pie in the oven during the holidays, that gives you that “homey”, secure feeling.

Even cats who have been declawed will “scratch” on a post or pad, leaving a scent message behind.

If your cat passes the scratches and detects the scent from an unknown cat or one he doesn’t like, he will stop and take a careful sniff. He may stay away from this area so that he doesn’t encounter this unknown/unfriendly cat. Cats in the wild avoid fighting and injury in this way. Cats in multi-cat homes may avoid cats they don’t like in the same way.

You most likely will NOT see your cats attentively sniffing the scratchers unless there is a disturbance in the “Smell”, say from a newly acquired cat or a cat whose scent has changed due to illness.

Cat on Scratcher — This cardboard scratcher doubles as a good lookout post.

Cats and scratching: where to put scratchers

Providing your cat with places to scratch will help maintain his claws, allow him to stretch and establish an olfactory map of his home. Multiple scratching posts around your home can help satisfy his needs and discourage him from choosing your new sofa as a scratcher. Watch which scratchers are used and relocate them as needed.

Doors and Windows

Cats are aware that the doors and windows in our homes lead to the outside world. Placing a scratching post or wall mounted scratching pad in these locations allows your cat to scent mark, which can help her feel more secure, especially if you have neighborhood cats that come to the windows and doors.

If you have persistent outside visitors that are distressing your cat, consider critter spikes on your fence or a motion-activated sprinkler.

Near Sleeping Places

It feels great to stretch after you wake up!

Near the Litter Areas

Another place to have a scratching pad is near the litter box – this can have the added benefit of reducing some of litter being tracked everywhere.

Cats and Scratching: Security through Scent

Scratching not only allows your cat to maintain his claws and have a good stretch, it is a way for him to establish a scent map of his home. This map not only includes his scent but the scents of other cats, if he lives in a multi-cat home. His own scent and those of the cats in his social group are comforting and help him feel secure. Scent marking may also promote harmony in multi-cat homes. Scratching is an important part of a cat-friendly home, promoting safety and security through scent in an environment that respects the cat’s amazing sense of smell.

Picking Up Your Cat

Posted on September 11, 2022September 11, 2022 by felinepurrspective_u3q4o6

Imagine being suddenly snatched up by a giant from your favorite chair. You are lifted up into the air, your legs flailing as you try to maintain your balance. Scary, huh?

Some of the more exciting scenes in fantasy movies include the hero or heroine being snatched up and taken away. In the Wizard of Oz, a troop of flying monkeys swoop down and grab up Dorothy and her dog, Toto, taking them to the castle of the Wicked Witch of the West. A giant ape carries Ann Darrow up the Empire State Building in the movie “King Kong”, as the audience shrieks and squeals.

Picking up your cat can be frightening for him. He often has little warning before he is airborne. He feels helpless and scared. But, you say, I pick my cat up all the time and he does not seem to mind. In certain circumstances though, he might redirect his fear as aggression and bite or scratch you, if you try to pick him up, say, to move him away from the vacuum cleaner.

Okay, so maybe you can coax him to go where you need him to by using treats or a target stick. But there still will be times when picking up your cat is necessary – for example, you may need get him out of the way of a car. What can you do?

Picking Up Your Cat Step-by-Step

The “Pick Up” behavior was a by-product of training Gus, a feral cat caught in a live trap when he was three years old.

When you picked Gus up, he often would thrash and flail in your arms, biting and scratching. He responds well to clicker training so I wondered if I could teach him to be picked up, in the same way he learned to sit and target.

We broke the behavior of being picked up into the following steps.

Kneel next to him on the floor and touch him where I would if I were going to pick him up. Give the verbal cue “UP”, then, click and treat.
Slide my arms around him like I was going to pick him up. Give the verbal cue “UP”, then, click and treat.
The next step was to actually to start to pick him up briefly, lifting him off the ground, with the cue “UP”. Click then treat.
Finally, I would pick him up off the ground for a few seconds while saying “UP”. I would click when he was off the ground, then treat him when I placed him back on the ground.
I “shaped” the behavior by picking him up and holding him longer and longer, always rewarding him afterwards.

Unlike most of the time we train our cats, “UP” does not require the cat to actively choose to do something. It involves a passive response. The click marks that the cat is being lifted up and will be rewarded in the near future. But, the “click” can also make your cat feel good.

Like Pavlov’s dogs, who salivated when they heard a bell, the “click” is a classically conditioned response. Once the click has been consistently associated with food or another reward, it ultimately triggers the same pleasurable emotions as the reward.

The “Pick Up” command was so successful that I taught all my cats this. Gus still squirms sometimes when the hold is taking him somewhere he does not fancy going… but, the biting has stopped! And he is rewarded for his patience with treats or head rubs when we arrive at our destination.

Although your cat is not in control of the situation when being picked up, if he hears the cue and the click, he knows what is going to happen, and can anticipate something good which should reduce his fear and anxiety.

Get Fat Cats Moving

Posted on September 4, 2022September 4, 2022 by felinepurrspective_u3q4o6

At the vet clinic where I work, we see quite a number of “fat cats”. Estimates of the prevalence of feline obesity cluster around 50%. Why are our cats getting fat? (See How Do I Tell if My Cat is Fat?)

Your cat has evolved to eat a diet rich in protein found in meat. His stomach is small and his GI tract is short.

Some experts estimate that a cat’s stomach is about the size of a ping pong ball but it clearly must stretch – when a cat eats a mouse, he often eats the whole thing, tail included!

When cats moved indoors, they gave up a free-roaming life in exchange for the safety of our homes and a consistent food source. Let’s look at the differences between cats in the wild and housecats.

Cats in the wild

Cat hunting — A cat pouncing on a mouse.

Cats in the wild hunt during the late afternoon to early morning hours when their prey is active
They sleep during most of the daylight hours.
A feral cat has about 3 hunting sessions – late afternoon, midnight and early morning.
He probably eats about 6-8 mice a day (180-240 kcal)
Most of his waking hours are spent on the prowl, foraging for food.

housecats

A cat plays with a toy near closed door during a cat introduction.

Some domestic cats live an indoor-outdoor life. These cats may supplement human-provided meals with mice and other things they catch outside.
Many cats live exclusively indoors.
Most housecats adopt their owner’s schedule and are awake during the day.
Housecats are either meal fed at set times or free-fed. Dry cat food may be left out, allowing the cat to “graze” during the day.

Housecats don’t have to expend time and energy to get their food – it is provided for them. When viewed this way, it is not surprising that there are many indoor fat cats. They don’t move around as much as their outdoor counterparts and don’t burn as many calories.

get fat cats moving: food and emotions

Neuroscience identifies 7 basic emotional systems: SEEKING, CARE, PLAY, and LUST are considered “positive”. FEAR, SADNESS, and ANGER are viewed as “negative”.

The SEEKING system is thought to be the strongest of the primary emotional systems. It’s what gets animals out looking for food, looking for a mate, looking for other resources.

When the SEEKING system is activated:

The brain releases dopamine, a neurotransmitter that makes you feel pleasure.
It is the rewarding feeling you get when you are looking for something and find it.
Once you’ve found the object of your desire, the brain shuts off the dopamine and other emotions are activated.

the hunting cat

Cats are skilled hunters. Hunting is an expression of the SEEKING system. The cat finds this activity pleasurable (dopamine is released) and rewarding (he enjoys the positive emotions that accompany eating). By providing your cat with food, he still enjoys the positive feelings that come with eating but the pleasure felt while hunting is not there.

Sedentary indoor cats with nothing to do may become bored and anxious. Many turn to eating as a self-soothing behavior, consuming more calories than needed – now, we have fat cats.

The seeking system is strong in the hunting cat – cats will stop eating to pursue new prey!

get fat cats moving for health and happiness

Divide your cat’s food into 4-5 meals – this gives the cat something to do and look forward to.
Make small meals a “hunting” experience!

FOOD PUZZLES

Although cats are born “freeloaders”, they can be persuaded to work for food using food puzzles. A food puzzle allows a cat to engage in foraging behavior, like the wild cat picking up the odd insect or lizard on his prowl.

Food puzzles help reduce boredom and engage cats mentally. Indoor cats in particular may benefit from using food puzzles.

HAVE FUN – TOSS A MEAL!

Toss your cat’s dry food, a piece at a time, down the hallway. He will have to chase the kibbles, using his hearing, sight and paws to bring down the “prey”. Older kitties may do better at catching kibbles if you “skid” them along a hard surface – skidding gives the cat a longer auditory signature to locate the food. (See “Cats Avoid Fighting Over Treats“).

WHEN YOU’RE NOT AT HOME

Timed Puzzle Feeder — This Cat Mate feeder can accommodate a food puzzle.

There are timed feeders like the Cat Mate that can accommodate some smaller food puzzles such as Doc and Phoebe’s no-bowl feeders. Alternatively, a Lickimat can be cut to fit into a timed or microchip feeder. Silicone ice cube trays or candy molds can also be cut to fit a feeder and promote foraging.

Hi Tech options: There are now feeders that will toss treats. You can start the sessions remotely through an app on your phone. The PetCube has a camera and microphone that you can use to talk to your cat and watch him. The Pet Cube is perhaps more geared toward tossing treats – it works well, though, with larger cat kibble such the dental diets and Greenies dental treats.

Of course, there are other reasons your cat may put on weight, for example, steroid therapy can be accompanied by weight gain. Your vet is your best resource to advise you on an appropriate calorie intake for your cat.

But it is rarely a mistake to pay attention to your cat’s behavioral health – take advantage of his superb hunting skills to get him moving! He will be healthier and happier.

When Your Cat Thinks Outside the Box: Part 1

Posted on July 31, 2022 by felinepurrspective_u3q4o6

A common complaint of cat owners is that their cat does not always use the litter box. This can be a nuisance – cat urine can have a strong odor particularly if the cat is not neutered or spayed. Soft stools can be a challenge to clean up. I am always surprised at how many people accept the “out of the box” incidents and use potty pads or towels to manage the mess. What can you do if this happens to you?

Why your cat thinks outside the box

There are a number of reasons cats may think “outside the box” and don’t use their litter boxes. Sometimes, it is a marking behavior. Other times, the litter box does not meet feline requirements, the cat is sick, or another cat is “guarding” the box. These are just a few of the reasons that may lie behind feline house-soiling.

Marking

Cats use urine to mark territory, advertise for a mate or let other cats know that Mr. Fluffy has been here (feces may also mark terrritory but urine is more common in domestic cats). The urine mark not only gives information as to the sexual status and general health of the marker, it also has a “time stamp” indicating when the mark was made. Cats, being solitary hunters, avoid confrontations to reduce the risk of injury. This “time stamp” may help cats avoid encountering each other.

Such urine marking is often but not always sprayed on vertical surfaces. It is typically characterized by small amounts of urine. This is usually a behavior of intact males and sometimes females but can occur with neutered or spayed animals. (Journal of Feline Medicine & Surgery 16(7):545, 10.1177/1098612X14539085)

PROBLEMS WITH THE BOX

Box is too small
Box is in a busy location near noisy appliances or in a high traffic area
Box is located near a window where neighborhood cats come
Box is not clean – remember to scoop at least once a day

A research team at Nestlé Purina found that cats prefer to use unused litter boxes. However, this preference for unused boxes did not seem to be due to odors. Cats did not seem to care whether or not the litter box smelled of urine or feces. But cats did not want to use litter boxes with actual urine clumps and feces nor did they want to use litter boxes with simulated urine clumps made from salt solution or “faux feces” made of gelatin. Ultimately, it appears that it is important to scoop frequently, removing physical obstructions from the litter box.

MEDICAL PROBLEMS

Pain and discomfort when eliminating can result in a cat associating the litter box with pain. Ongoing pain can be frightening for a cat and cause him to be anxious, exacerbating urinary and gastro-intestinal problems. The cat may choose not to the use the litter box he associates with the painful elimination.

When your cat thinks outside the box, it could be due to medical issues, including:

Urinary tract infections
Bladder stones
Arthritis – can make it difficult for a cat to squat or step over a high side to get into the litter box
Constipation and diarrhea
Cognitive dysfunction in older cats ( Cat Dementia: How Can We Manage It?)
FIC (feline idiopathic cystitis) – (see “Is My Cat Sick from Stress”)
Hyperthyroidism
Diabetes
Kidney disease

Social problems

The litter box is being “guarded” by another cat
The family dog is coprophagic and “haunts” the litter box
A toddler wants to “play in the sandbox” too
A house guest kicks his shoes off and they hit the wall; the noise startles the cat in the box

When your cat thinks outside the box – make an appointment with your veterinarian. Your vet can:

Assess your cat’s overall health
Collect blood, urine and stool samples for diagnostic screening
Take X-rays if there are concerns about bladder stones or arthritis
Prescribe pain medication
Prescribe anti-anxiety medication while house-soiling issues are being resolved

It is wise to act promptly when house-soiling issues arise. When house-soiling continues for a long time without resolution, we run the risk of “coping behaviors” becoming habits. For example, a cat may choose to urinate in the shower or bathtub, defecate in a quiet corner in the front entryway, or eliminate right next to the box. Once these behaviors are established, it is sometimes difficult to break these “bad” habits.

Our next post will look at what you, the cat guardian, can do to encourage new habits and help remedy house-soiling, when your cat thinks outside the box.

Coat Color and Temperament in Cats

Posted on July 3, 2022July 3, 2022 by felinepurrspective_u3q4o6

Does the color of your cat’s coat mean anything? Is there a link between coat color and temperament in cats?

Black cats are often associated with the occult; orange cats tend to be regarded as friendly. Calico and tortoiseshell cats – those cats with tri-colored coats – are considered strong-willed and difficult to work with. There is even a term – “tortitude” – to describe these cats!

In a study published in 2016, researchers at UC Davis decided to look into whether there is a link between coat color and temperament – in particular, do cats with particular colors of coats tend to be more aggressive? Cat owners were recruited online to fill out a survey about their cats. The team received 1,274 responses that they analyzed with statistics.

Owners scored their cats for

aggression toward humans
aggression when being punished, petted, or brushed
aggression when in the veterinary clinic

Aggression toward humans scored the frequency with which a cat reacted with aggressive or affiliative behavior to people. A 6 point scale was used ranging from 0 = never through monthly, weekly, up to 5 = daily. Behaviors included hiss, bite, slap/scratch, bite/scratch and stalk (play), groom/lick, curl up next to, approach and greet with head/body rubs. The possible range of scores was 0-20.

Aggression from handling scored the likelihood that the cat would react to being punished, petted or brushed by hissing, biting, slapping or scratching. Scores ranged from 0 = unlikely to 3 = very likely. The maximum score possible was 27. Aggression during the veterinary visit was also scored from 0 = likely to 3 = very likely but with a maximum score of 9.

Overall, the aggression scores are rather low in all three categories. For example, in the “human aggression” category, high scores were 2-3 out of 20. Female cats had higher scores overall but the research team felt the difference to be small enough that they could combine the sexes in the overall study.

Coat color and temperament – findings

Tortitude

The calico and tortoiseshell cats were found to have some of the higher scores (2.47) for aggression toward humans (Gray and white cats scored 2.26 – so not much different than the tri-color cats).

These scores are not very high scores out of a possible 20.
Calico/tortoiseshell cats are predominantly female (the tri-color pattern is linked to the X chromosome making the combination of 3 colors very rare in male cats). Female cats were found to be a little more aggressive than male cats in this study and this sample would have had more females.
Perhaps, the stereotype of the “strong-willed” tri-colored female cat affected how respondents scored their cats.

other findings

Gray and white cats, both female and male, were more aggressive toward humans and when being handled.
Black and white male cats scored higher than other groups of male cats in human-directed aggression.
Surprisingly, there were no significant differences in aggression among cats at the veterinary clinic.

Although the results of this study seem to support the stereotypes of cat color and aggressive behavior, e. g. “tortitude”, it is best to take these results with a grain of salt.

Overall, the scores for aggression to humans and when being handled were quite low.
The questionnaires were completed by the owners and there will be some differences in the way people interpret and score things.
Stereotypes may have affected how respondents view their cats and scored them.
The questionnaires did not involve a random sample of cats and cat owners but cat owners who voluntarily signed up to fill out the forms. These could be potentially more interested and “saavy” owners.
There will be differences in how people approach and handle their cats.

At the Battersea Dogs and Cats home, cats were more friendly with humans after the human volunteers watched a video demonstrating how to interact with cats. ( see “Practical Guidelines for Interacting with Cats” )

The link between coat color and aggressive behavior does not seem particularly strong. Such information could be useful to cat owners, shelters, and veterinary clinics to allow them to anticipate what behaviors they may encounter. But as the saying goes, “Don’t judge a book by its cover”. A cat’s coat color is only part of the story – it is important to assess each cat as an individual. Approach him or her respectfully following the CAT guidelines.

Managing The Indoor Cat Fight

Posted on April 10, 2022August 4, 2024 by felinepurrspective_u3q4o6

Aggression between Cats — Two cats engage in a spat while waiting to be fed.

In spite of our best efforts, things can go wrong and our cats confront each other aggressively. You may have adopted a new cat and he escapes the room you are keeping him in while introducing him to your resident cats. Something may startle the cats, say an outdoor cat comes to the window and one cat attacks a housemate in a bout of redirected aggression. Separation is the immediate solution to these unplanned events.

Indoor Cat Fights vs outdoors

There is nothing as dramatic as a cat fight. Two cats face off, fur standing on end, yowling and spitting. Often, one cat may slowly move away, all the time presenting his side to the other cat (to look larger); his back may be arched. Depending on the motive for the standoff, the remaining cat may just stand his ground and allow the other to leave or he may pounce, and the two cats grapple each other, biting, clawing, kicking, and the “cat ball” rolls away until it stops and both cats take a breather.

Unlike cat fights outdoors, the indoor cat fight can be more aggressive and more likely that either a person or a cat gets injured as things are in such close quarters. There may not be the ritual posturing and howling of a territorial cat fight outdoors. There may not be the opportunity for one of the cats to get away and there is not the extinction in fighting that can happen once one cat leaves the other’s territory.

How do we break up the indoor cat fight?

Move calmly and deliberately – avoid fast or jerky movements
Close doors to the area the fight is happening.
Distract the cats momentarily so that you can block them from seeing each other.
Herd the cats away from each other.
Lure the cats into separate areas (rooms) – put a door between them!
When all is calm, evaluate cats and people for injury. Seek medical attention if necessary.

Resist the temptation to scruff both cats and pull them away from each other. You will most likely get scratched, and, worse, get bit. Not only may you require medical treatment, your bond with your cat or cats will suffer.

Scruffing does not calm an adult cat and can actually injure him. Many people have been bit while scruffing a cat – the kitten reflex is long gone.

breaking up the indoor cat fight

A broom can be handy to gently separate fighting cats. It you anticipate aggressive encounters, attach some cardboard to the broom.

Distractions: If a bag of cat treats is at hand, shake it. Try scattering treats on the off-chance it may distract them. Try pulling a toy on a wand or shining a laser pointer on the floor between the two cats. Avoid using really loud noises to distract the cats on the off-chance you may frighten them. Adding fear to already heightened emotions can make the fight worse.
Block visual contact: Try to slide some sort of barrier between the combatants. This may be a broom, piece of cardboard, or a sofa cushion.
Herding/Luring: Once out of sight of each other, try to direct them away from each other by tossing treats in opposite directions. If food is unsuccessful, “herd” one cat (preferably the more aggressive cat) with your barrier gently away from the other toward a place where you can separate the cats by a closed door.

A towel or blanket can be used as a barrier, albeit a flimsy one. If you can keep some tension on the edges and target the aggressive cat, this may be enough time for the other cat to get away, for example, and climb a cat tree. You can also try and cover the aggressive cat with the towel. Be aware that fighting cats are tense and coiled like springs – they move extremely fast and may just outrun your well-aimed towel.

Be careful not to succumb to the emotion of the moment – hitting either cat with a broom, cardboard, or cushion will not be effective.

if you have help

DO ask your “helpers” to speak in quiet, “happy” voices. Have someone try to divert the cats’ attention with a wand toy or laser pointer. Be ready to slide your barrier in to block visual contact as soon as the cats are momentarily distracted.

DO have your “helpers” open the door to a room where you can herd one of the cats to. If there are additional materials for barriers (cardboard, broom, sofa pillows), have them herd one cat into a room while you work with the other or vice versa.

Other tools in the indoor cat fight

Spray bottles with water – these may stop some cats in their tracks but be warned there are cats that will keep going even if you soak them down. The spray also means you will need to get close to the cats and may be a casualty of redirected aggression.

Noise makers – Cans with pennies can be effective to distract the cats. Avoid the use of really loud noises such as air horns – in close quarters, these will be really loud, adding fear to already heightened emotions.

Rattling the food container elicits a positive emotion. If you can distract the cats and separate them, you can try and lure them with treats into separate areas.

be proactive!

Materials to separate fighiting cats — A basket holds a towel, jar of treats, and a spray bottle of water. There is a cardboard barrier behind the basket.

If you are introducing cats or trying to correct redirected aggression due to, say, outdoor cats, have some “emergency” stations set up in areas close to where aggressive encounters may occur. Stock each ER station with:

A piece of sturdy cardboard – you can make a “paddle” by attaching it to a pole. This will keep you out of the line of fire as you try to herd a cat.
A thick, large towel
A jar of treats and a can of pennies
A spray bottle of water
