If You Own A Cat You Need To Know The Signs Of Cat Aging

Last Updated on

Sometimes our lives seem to go on automatic pilot or so it may seem when we look back at a period of time and wonder how it passed so quickly.  This can be the case when we realize that a beloved pet is getting older. Our pets getting older is a thought that we may push to the back of our mind but eventually it does catch up with us.

There are different stages of aging and for quite a few years cats meander along in the mature stage and then at some point they will begin to exhibit some signs of older age. 

Cats become officially old at around 11 and geriatric around 15 so remember that when you are dealing with your elderly kitty extra patience will be needed in addition to being attuned to any changes that might need a trip to the vet.

Typically you may first notice that your cat isn’t quite as agile as he used to be and may show signs of difficulty jumping to some of his favorite high places.

Typical/General Signs Of Aging In Cats

Disclaimer: The following information is to assist the reader with common problems that may occur in aging cats however is not intended in any way to replace advice from a veterinarian but rather supply general information.  A veterinarian diagnosis is essential for medical issues.


Older cats c​ommonly have problems with their vision. If you notice vision problems, seek professional help. If treated in the early stages there will be a greater chance that the condition can be treated. 

Cats, like humans will rely on using a different sense, such as smell, if they have vision loss.  Often vision loss can be happening slowly over a period of time. ​


For a cat owner often an initial sign of cancer is noticing a lump or bump that wasn’t always there. Lumps and bumps can have many different causes however your vet will assess the possible causes and determine the best course of action.  

Like cancer in humans there have been huge strides in pet oncology and some cats have a good prognosis if the cancer is caught early enough or is treatable​ so don't ignore newly found bumps. ​It may mean nothing and just be an old war wound but it is far better to know for sure.


Of the two types of thyroid ​conditions, hypothyroidism and hyperthyroidism, it is hyperthyroidism that is more common in cats.

Symptoms of hyperthyroidism in again cats can include loss of weight, rapid heartbeat and an increase in hunger.  As older cats commonly lose weight with age it can be difficult to distinguish loss of weight with normal ag​ing of the cat.


Diabetes Mellitus in cats occurs when the pancreas cannot produce enough insulin.  Some of the signs of this lack of insulin can be increased thirst, loss of weight, excess urine production along with an insatiable appetite.  

Being overweight is another factor and if your cat is diagnosed with diabetes his weight will need to be controlled within healthy levels. 

If your cat is an indoors cat these signs ​may be more obvious than if your cat is often outside for eating, drinking and urination, as these vital signs can then be missed.

Our elderly cat developed diabetes at the age of 14 and required insulin injections twice daily before meals. He had periodic visits to the vet to have his blood glucose levels checked. We managed his condition well and he did pass away some three and a half years later.

For a thorough description of feline diabetes and how to administer insulin this is a​​very good article from Cornell University, College of Veterinary Science. ​


Tartar does build up on a cat’s teeth and the teeth ​need to be professionally cleaned from time to time. Often the first sign to cat owners of teeth problems is that the cat has bad breath however at this stage disease has probably been present for some time.

Aging cats can manage with no teeth and still eat a healthy diet.  ​ If possible you want to avoid teeth problems which if left untreated may then lead to gum problems. 


The ​grooming habits of​ cats ​decreases ​with age and their fur may become matted or untidy. On the ​flip side, your cat may display sign of over-grooming and even lick patches of skin bare.

The nails get longer and thicker any may be hard to trim. This may be something that you would prefer the vet to take care of​.

​Arthritis and Joint Pain

Arthritis in cats means that they can't move as freely as when they are younger. ​You ​may notice subtle differences in movement ​​such as stiffness when bending to reach a food or water bowl and difficulty getting to a comfortable lying position​, less play and difficulty climbing stairs.

​Ensure​ your cat is not overweight as this will place an  unnecessary burden on already aching joints. Your vet may prescribe an anti-inflammatory medication or a joint supplement.  It is vital that these medications are prescribed by a vet.

Visit The Veterinarian

You may find yourself visiting the vet more frequently. For many years our cat did not go to the vet apart from immunizations and the occasional complaint.  This changed as he became older. 

If you are unsure of any changes you are seeing such as the cat eating more or being constantly hungry, drinking more, showing stiffness in movement, having accidents or not using the litter box and so on, it is time to visit the vet.  

Behavioral Signs of Aging in Cats


Displaying signs of aggressive behavior may indicate that the cat is stressed or anxious and this could be because the routine in the household has changed.

Perhaps a family member has left home or there is a new baby or maybe pain and illness are causing these changes. He may begin to meow more and with aggression for no particular reason.

Be patient if your elderly cat starts displaying behaviors that may seem out of character.  If you feel that something is not right then get professional help.

​FCD or Feline Cognitive Decline

You may have read of FCD or Feline Cognitive Decline  on the internet in relation to your cat’s age. This is an instance where your vet will give the diagnosis. Behavior changes can be linked to physical changes and your vet may prescribe or suggest treatment to help with these changes. 

Personality Change

If your cat has always been rather aloof and disliked being held or carried when he was younger, he may now be happy to be picked up and even carried around. This is also a nice time to have a little chat to kitty.


​Sleep and Play

Your senior cat will sleep more as he ages and​ won't have the energy he had once.
He won’t play as much or for as long as he used to but ​still enjoys human interaction. 

Playing with a wand toy is always stimulating for a cat even if the playtime is now short and sweet. The beauty of a simple wand toy is that you are in control of ​the speed with which you wave the ​wand so ​it is super easy to ​adapt ​for older cats and their energy level.

Another great toy for older cats ​is the interactive laser toy. Your cat ​may wander off when he has had enough but ​he will return. It's a bit like going back to the buffet when you know you have really had enough to eat.  Now we don't want to set kitty up with psychological issues but laser pointer toys are entertaining for cats.

Litter Box ​Problems

Your aging cat may develop litter box problems. This c​an be attributed to a variety of ​ reasons, for example, an underlying medical problem such as a urinary tract infection, stress or anxiety, constipation or kidney stones.  The vet can treat the medical issues and you can help with the behavioral issues. 

​Try to leave the litter box where it has always been, making sure the cat can enter and exit the box easily. A low sided litter box is good for elderly cats. Check the cleanliness of the box or the type of litter being used.  These are all things that you can do to help your cat. 

​When you visit the vet, explain the behaviors you have seen. This may mean that you pay more attention to what kitty is doing at certain times of the day.  The vet will also want to know if you have taken any steps to​ treat the problem.  This may be behavioral or perhaps a change in diet and specifically the steps you have taken to help alleviate the problem​.

Take Photos Or Videos Of Your Aging Cat

Our cat passed away not so long ago and I have cherished​ looking at the many photos, now that some time has passed, the whole family took of the cat over the years.

However as nice as the photos are, it is however the short videos that are really heartwarming and heart wrenching at the same time.  Take a few minutes to make some short videos to go along with the no doubt countless photos you already have.
