Cats Communicate by Smell – Semiochemicals in Cat Communication

Posted on October 27, 2023October 29, 2023 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.

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.

Glands producing pheromones — Locations of the glands that produce pheromones in the cat.

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 October 22, 2023 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:

Athena, aged 18 years, forms her own social group. She tolerates the other cats but does not snuggle, groom or otherwise interact with them.
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.

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.

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?

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.

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.

Cat dementia: How can we manage it?

Posted on November 7, 2021 by felinepurrspective_u3q4o6

At the veterinary clinic where I work, I often hear people say when I ask about their cat’s activity and play, “she sleeps most of the time and meows a lot at night. She doesn’t play – she’s an older cat”. How much of these behaviors is due to “normal” aging? How much is due to other medical conditions or a declining brain?

Cognitive Dysfunction Syndrome in cats or cat dementia refers to the decline in mental abilities associated with aging.

Cat dementia results from damage to the brain. As your cat ages, the the numbers of molecules called free radicals are no longer balanced out by the antioxidants in his body. These free radicals are reactive and cross the blood-brain barrier, damaging cells in the brain.

Changes in blood flow to the brain can also cause damage by starving the neurons of oxygen. High blood pressure, heart disease, anemia – are all conditions that alter the flow of blood to the brain.

How can we tell if our cats are undergoing mental decline? Is there anything we can do about it?

VISHDAAL – behavior changes

Changes in behavior can indicate if your cat’s mental state has declined. The acronym VISHDAAL summarizes the behavior changes we need to monitor in our senior cats, from the most prevalent (vocalizing) to least frequent (changes in learning and memory).

V = vocalization
I = changes in interaction with us and other pets
S = changes in sleep-wake cycle
H = house soiling
D = disorientation
A = changes in activity
A = anxiety
L = learning and memory

How do we sort out behavior changes due to disease and those due to declining mental capacity?

Changes in behavior signal the onset of cognitive decline but they may also arise from other health issues:

Cats with untreated high blood pressure or hyperthyroidism may meow at night (vocalizing).
Cats with untreated hyperthyroidism may be restless and beg us for food (changes in interactions and sleep).
Kidney disease can be accompanied by increased thirst and urination which may result in house soiling (house soiling)
Cats with osteoarthritis may have difficulty accessing the litter box (house soiling).

behavior changes: disease vs Dementia

Regular veterinary exams and diagnostics can identify medical conditions such as high blood pressure, hyperthyroidism, and osteoarthritis. If behavioral changes persist after treating these other medical conditions, your cat may have CDS or cat dementia.

Cat dementia is a “diagnosis of exclusion” – it is the diagnosis that remains after all the other possible diagnoses have been eliminated. Cat dementia will usually have a slow onset and behavioral symptoms will gradually get worse.

Cognitive Dysfunction (CDS) cannot be cured but management can reduce the symptoms and improve the Quality of Life for both you and your cat.

managing cat dementia

environmental enrichment/modification
dietary supplements
therapeutic diets
medication

Environmental enrichment/modification

In the early stages of cat dementia, enrichment increases mental stimulation, leading to the growth and survival of neurons, preserving the thinking processes. Enrichment should be tailored to the individual cat. For example, some cats prefer high places; others are “ground dwellers”. Arthritic cats will not have the range of motion of healthier cats but will still enjoy play that does not require lots of jumping.

Ways to enrich your cat’s environment:

play – interactive play and toys
scent enrichment – catnip, silvervine
food puzzles
motion – climbing (cat trees) and exploring (cardboard boxes)
supervised outdoor access

As CDS progresses…

Environmental changes become stressful and confusing. Cats with severe cat dementia need an environment that does not change much – daily routines and feeding schedules must be maintained. Litter boxes and feeding stations need to stay in the same place.

A cat with severe CDS may benefit from a “room of his own”, with easy access to his resources. Changes that need to be made must be done slowly. If you need to move a litter box or feeding station, do it gradually over a number of days so the cat can still find it.

Environmental modifications

Modifications to the environment of the cat with dementia should take into account the behavior that she is exhibiting.

Cats that constantly beg for food may benefit from a timed feeder at night or treat balls.
Cats with house soiling tendencies may need more litter boxes and ones that are easily accessed, with a lower entry for example.
Cats that become disoriented and confused may benefit from a night light and radio playing soft music.

Dietary Supplements

Dietary supplements in general seek to restore the balance between the activity of antioxidants in the body and the production of free radicals. Antioxidants give up electrons to the free radical, effectively “neutralizing” it so that it is no longer reactive. So, these supplements usually contain antioxidants.

SAMe: (S-adenosyl-methionine) aids in the production of glutathione, an antioxidant. When elderly cats were supplemented with SAMe, there was improvement in cognitive tests. SAMe is best used pro-actively – it is most effective in cats in the early stages of cat dementia.

Proprietary supplements containing vitamins, resveratrol (antioxidant), and fish oils are on the market but there is no clinical data testing cats for these at this time.

other supplements

Melatonin: hormone in the body that is thought to promote sleep. It also has antioxidant properties. Melatonin declines with age.

Pheromones (Feliway), Zylkene, Anxitane (L-theanine) may help reduce anxiety in cats that are disoriented and may promote sleep.

Therapeutic diets

Therapeutic diets containing antioxidants and fish oils have been shown to help cat dementia.

Feline Mature adult Hill’s Pet Nutrition
Purina Pro Plan Age 7+
Hills prescription diet j/d with fish oil for osteroarthritis

Diets that reduce anxiety may also help with cat dementia

RC Calm diets
Hill’s urinary support

Medications

Selegiline: licensed to treat dementia in dogs. Like the dietary suplements, it aims to reduce the production of free radicals. Selegiline stimulates the production of enzymes that eliminate free radicals.

Anxiolytics: Prozac, gabapentin and clonazepam are used to treat dementia by reducing anxiety.

boxes as enrichment for cats — Boxes can be source of enrichment for senior cats.

If you feel there has been a significant change in your cat’s behaviors, keep a journal or log and make sure to mention it at her next senior exam. Start the conversation with your vet about cat dementia and how to manage it!

My Cat Meows at Night

Posted on May 23, 2021May 23, 2021 by felinepurrspective_u3q4o6

It’s 1:50 am – you know by the red numbers on your alarm clock. That darn cat meows at night and has woken you up once again.

What is happening?
If this is a new pattern, it is time for a vet visit to make sure that there is not a medical cause underlying the nocturnal activity. High blood pressure and hyperthyroidism are two conditions that can contribute to meowing at night. Treating these conditions may solve the tendency toward night-time activity and meowing.

If your cat has had a physical exam recently and has no untreated health issues, there may different things underlying the “feline nocturnes”. In the wild, cats hunt at dusk, nighttime and dawn when their prey, small rodents, are foraging.

Our indoor cats usually adapt well to being active during daylight hours and snoozing at night.
If this is not the case, what can you do to reset your cat’s internal clock?

Perhaps your cat meows at night because he is bored and awake. He may be seeking your attention.

Make sure your cat is active during the day. Give him some play sessions during the day; engage him in foraging behavior with food puzzles.
Establish a night time routine. Cats thrive on routine – it lets them know what is going to happen. Pets can be as good as a clock when reminding you for dinner. Let’s come up with a sequence of activities that signal that the household is slowing down and ready for sleep.

Bedtime Routines when your cat meows at night

Play/Treat time: My cats look forward to treats before bed every evening. After dinner and TV, the litter boxes are scooped and then – IT’S TIME.
All 4 cats proceed to the hallway where they take up their stations and wait to have treats tossed to them. After that, it is time to settle down and they each go to their sleeping place and tuck in.

Your cat might enjoy a play session before treats. This session does not have to be long – 10-15 minutes should do the trick. After that – IT’S TIME FOR BED!

Foraging toys: Try leaving some foraging toys (food puzzles) out and turn in. Again, this is a bedtime routine – you put the toys out and you turn in.

You can try closing the bedroom door. Of course, for many cats, if you close a door, this is the place they have to get into and will shake and rattle the door for access.

My Cat meows at night – Does he need a room of his own?

You have tried more play during the day and you are putting out food toys at night – still your cat meows at night.

This may be time for some “tough love” – after all, you need your sleep. If you have the space, give your cat a “bedroom” at night. This could be a spare bedroom or walk-in closet, someplace where you can close the door. Put all his resources (litter box, toys, water) in this room. Put a “calming” pheromone diffuser in this room.

When you are ready for bed…

Take kitty to his bedroom
Give him a snack.
Close the door – do not respond to crying at night once the cat is in the room.
He will be safe in there until you get him out in the morning.

While this may seem “cruel”, remember that cats are “socially flexible”. They are able to live socially with humans and other animals but do very well on their own. They don’t get “lonely” the same way we do.

to have a quiet night…

Be sure to give your cat regular, daily playtime and activities. This may be a good time to review how you are feeding your cat – leaving out a food bowl filled all the time is like having a bowl of potato chips out all the time. Feeding can be self-soothing behavior for a bored cat.

3-4 smaller meals gives kitty something to look forward to – you can put one of these meals in his room for the night.

The Takeaway: if your cat meows at night, try giving him something to keep him busy – some extra play during the day and a bedtime routine just might silence the “kitty nocturnes”.

Cats are territorial

Posted on January 23, 2021 by felinepurrspective_u3q4o6

Cats are territorial. What does this mean for cat guardians?

An outdoor cat’s home range is the maximum area he roams and hunts in. Within the home range is a smaller area that the cat will actively defend – his territory. Inside this defended area is a smaller area called the “core territory”, where the cat can rest, has shelter, and feels safe from predators and other cats.

Free-roaming cats establish their territories around food supplies. They remain solitary hunters and don’t share prey with other cats. Access to food, water and places to rest and shelter are some reasons why cats will fight with each other. Having a secure, established territory is essential to the free-roaming cat’s survival.

When cats move inside, their territories shrink and the house becomes the territory. Home ranges still apply for cats with outdoor access. Within the house, cats will choose their core territories – their safe places where they go to nap and feel secure.

In my 4 cat household, Athena and Marley choose the master bedroom as their safe place, with comfortable resting places, water and access to a litter box; Gus’s safe place is the back office; Zelda floats between the office and the master bedroom.

What are the threats to the territory of the indoor cat?

Outdoor cats: Neighborhood cats that come in the yard or come to the windows of the home may be seen as a threat by the indoor resident cat(s). The threatened cat may strike out at humans or other pets nearby because he can’t get at the cat outside but is prepared to defend his territory.
Other resident cats: Cats are territorial and remain territorial when they are kept indoors. There are often multiple social groups in a multi-cat home. Cats of one social group may guard resources such as litter boxes, food and water from cats of another group.
People, other animals, inanimate objects: Although territorial behavior usually involves other cats, cats may see other species or things as threats to their resources and well-being, as threats to a secure territory.

You will see your cat rubbing her face against walls and furniture. She is depositing pheromones from glands in her face to mark the area as safe. Cats also routinely mark areas by scratching, releasing another pheromone from glands in their paws, an olfactory signal to other cats that they passed by. This is normal behavior that the cat guardian needs to accommodate by providing scratching post and cleaning the “whisker walls” sparingly. Maintain the colony scent..

If your indoor cat perceives a threat, he may feel the need to mark the house with urine (sometimes feces) to establish the house as his territory. He also may respond to the “threat” with aggression.

It is up to the cat guardian to understand that cats are territorial and ideally modify the environment before marking or aggression starts.

What you can do:

Diagram social groups cats — There are 3 social groups in this 4 cat household.

Outdoor animals: Restrict access to your yard if you can. “Critter spikes” can deter some cats and raccoons from scaling fences. A motion activated yard sprinkler can also be effective. You may wish to cover windows with static cling window film so that cats can’t see out.
Multi-cat conflict: Identify the social groups in the household. Make sure resources are spread out and all the cats in the household have easy access to resources of their choice. Pay particular attention to the dynamics of feeding, using litter boxes, and resting. Make sure that all cats have an opportunity to exercise their hunting skills through play. Set up time-sharing for social groups if necessary.
People, other animals, inanimate objects: Isolate your cat from the stressor or desensitize her if possible. For example, if she feels threatened by visitors, train her to go a safe place out of reach when visitors arrive. Request that visitors refrain from interacting with your cat unless she chooses to interact. Make sure to reward her with something she likes in her safe place. She may elect to leave the room or observe from her safe place.

The Cat Friendly Home: Guiding Your Cat’s Scratching Behavior

Posted on July 10, 2020August 8, 2020 by felinepurrspective_u3q4o6

The Cat Friendly Home: Guiding Your Cat’s Scratching Behavior

You know that scratching is a normal cat behavior – but does she have to scratch the new sofa you spent hundreds of dollars on? Should you have her declawed?

Sharing Your Home with a Clawed Cat…

Synthetic feline pheromones can be purchased from pet stores.

To guide your cat’s scratching behavior, we have to communicate with him and let him know where to scratch.

Cats communicate in a large part by smell ( A Cat’s world: Smell) Pheromones are chemicals that convey messages between members of the same species – they are detected by smell. There are several feline pheromones that have been synthesized and are commercially available.

We can use facial pheromones and interdigital pheromones to guide your cat’s scratching behavior.

Getting the message across..

Feliway Classic tells your cat that this is familiar territory and there is no need to mark it – DON’T SCRATCH HERE
Feliscratch gives an olfactory as well as visual message (scratch marks) that says – SCRATCH HERE

The Plan…

Place a scratching post near the area that is being scratched.
Apply Feliscratch to the scratching post
Using Feliway Classic (or Comfort Zone Calming) spray, spray the areas where scratching is not desired. You may wish to spray a towel or throw and place this on or near the scratched area.
You will need to apply these daily for at least a week. After a week you can apply as needed.

Facial Pheromones

This pheromone is released when your cat rubs his cheeks against things, say the corner wall. He is marking the area as a safe place.

Feliway Classic and ComfortZone Calming come in diffusers and spray.

Appeasing Pheromones

There are synthetic versions of the pheromones released by the nursing mother cat. This pheromone assures the kittens, blind at first and unable to move fast, of their mother’s presence. It helps the litter mates to bond together. This has practical uses – it helps keep the kittens together if Mom needs to go hunt.

Feliway Multicat and ComfortZone Multicat control come in diffusers.

Interdigital Pheromone

This pheromone is released by glands in your cat’s paws when he scratches. It helps mark boundaries and, combined with your cat’s signature scent, lets other cats know “Mr. Fuzzy was here at noon”

Feliscratch comes in a box of pipettes. The liquid in the pipettes is applied to a scratching post to encourage your cat to scratch.

Spray the scratched area with Feliway/ComfortZone

Apply Feliscratch to the scratcher you have chosen to be near the scratched place.

Marley checks out the “Feliscratched” scratcher.

During the Training period, you may wish to have nail caps (Soft Paws) applied to your cat’s claws. These are soft plastic caps that are glued onto your cat’s nails.

Applied every 4-6 weeks
Use permanent adhesive
But…some cats just don’t like them and chew them off!

Nail Trims for the Comfort and Safety of You and Your Cat…

Trim the end of the claw. Avoid clipping the pink area.

Start nail trimming early in life
Use positive reinforcement: treats, play, grooming, head rubs
Trim every 4-6 weeks
When trimming some cats, trim 1-2 nails at a time and do the trim over a week
As cats get older, their nails may get thicker and their joints stiffer, so they don’t groom as much. The nails can grow into the paw pad. Nail trims can improve these cats’ quality of life!

Declawing – an amputation

The Details of Declawing

Removal of the last bone of the cat’s toe
There are “good” and “bad” declaws: “good” declaws disarticulate the last (3rd) joint
Risk of lameness and behavior problems due to nerve damage
Weight is no longer supported by the junction of the 2nd and 3rd bones – it is supported by the end of the second bone which is painful.

What’s inside your cat’s toes – claw is sheathed when cat is relaxed. He must extend his claws to use them.

In a declaw surgery, the bone with the nail bed is removed.

A Final Word…

Guiding your cat’s scratching behavior can be a rewarding experience – after all, YOU are communicating with ANOTHER species!

Offer a variety of scratching stations located in strategic places:
Near doors and windows
Where the people hang out
Near the litter box
Near the sleeping area
