The best diet for an old cat consists of mainly animal protein. Cats need animal protein to survive because they are obligate carnivores. The major ingredient in the diet of your older cat should always be animal protein. Foods that are gravy based are also recommended because of the moisture content.

Senior cats (unlike dogs and humans) require an increase in energy requirements as they age, rather than a decline in caloric intake, as is usually associated with older age, as outlined in this article from Science Direct.

Feeding your senior cat higher levels of protein also helps to prevent the loss of lean muscle mass.

Manufacturers of cat food make formulations specifically for senior cats, that include added supplements that will assist senior cats into old age. Commercial cat food for your senior cat will not require any additional dietary supplement, because it is already included in the food.

If your cat is fed an entirely home-cooked diet, it may be a good idea to supplement with a multivitamin. Ask your vet if there is anything you need to do, to optimize the home cooked cat’s diet, further.

Key Takeaways – Best Cat Food For A Senior Cat?

The best cat food for a senior cat is wet food that:

  • Has quality protein as the main ingredient
  • Is specially formulated for older cats
  • Is either canned or in pouches

A mature cat is less inclined to drink water as they age. If your senior cat eats and prefers the pate style of wet foods, no problem, the food can be mashed and some liquid added.

One problem can be, that sometimes the cat just wants to lick the gravy from cat food containing gravy. Even if this is the case, usually the cat will return to eating the food, even after a little taste of gravy licking.

Our senior cat always licked the gravy first, but always returned to eat the food.

I am afraid to say that I have been guilty of wanting to eat the frosting rather than the cake. Maybe the cat had seen my less than desirable cake eating habits.

Older Cats Can lose Sense of Smell

Something else to consider, is that a cat’s senses start to fade as they get older, so they might not be able to smell quite as keenly as when they were younger.

This was quite noticeable with our senior cat’s ability as he aged.

Food that once brought him running now had to be placed almost under his nose.

The four different foods reviewed here are suitable for older or senior cats.

Your choice might come down to the points listed below:

  • the price point of the cat food for old cats
  • or the ingredients to best suit an old cat in the cat food

We might think that our senior cat will get bored with only one or two flavors of cat food, however that does not seem to be the case with cats.

We are the ones who think a wide choice of flavors is desirable, cats not so much.

Our cat was a wonderful rat catcher in his youth (yes, rats in the neighborhood).  He didn’t seem to get upset by the fact that all rats probably tasted the same.

What If My Old Cat Prefers Dry Food?

Many cats prefer dry cat food and this may be the case with your senior cat.

Older cats with dental problems can have trouble managing dry kibble, even though the food may be excellent quality. Wet cat food can be easier for older cats to manage.

To overcome this problem try adding a a small amount of wet food as a topper. This will moisten the dry food and make it easier for the cat to manage.

Old Cats – Importance Of A Healthy Body Weight

An integral part of cats remaining healthy into old age is sustaining a healthy weight as they age.  Older felines can easily become overweight.

As cats age they slow down and become more sedentary in nature. Don’t give your cat treats too often as this will be a sure path to weight gain. Obese cats have more of a risk of developing diabetes.

However the reverse can also be true and some elderly cats can lose weight and become very thin, even skinny and quite fragile.

Our cat was always in the normal weight range. Sometimes we had to cut back a little on the kindness (too may treats) for him to maintain a healthy weight.  

However, when he reached old age he became very thin as a result of several health conditions. Trips to the vet became a regular occurrence and he was on first name terms with all of the staff at the clinic.

Underlying health conditions can be a consideration with weight gain or weight loss, and once again this is when it is time to visit a veterinarian for an assessment of body condition and any possible underlying health conditions.
