old cat eating cat food

These days, it’s not uncommon for a cat to live over the age of fifteen. Some can live well into their twenties. But nutrition often plays a major role in your senior cat’s health, especially if they have certain health conditions such as arthritis or diabetes. The best cat food for older cats should contain all of the important, supportive vitamins, minerals, and nutrients that are designed to aid in digestion, relieve joint inflammation, and help them to thrive at age twenty and beyond.

But even the best cat food can contain additives and fillers that offer no real nutritional value to seniors. Seniors go through many changes as they age, which can make them more vulnerable to disease and medical problems. That’s why I decided to create a buyer’s guide that will help senior cat owners to choose a product that will actually help their pets to continue to thrive by offering a different formula that you can’t get with cat formulas that are designed for younger cats. Instead, food designed for seniors will meet their special nutritional needs. I’ve also included six products that contain all the right ingredients for our seniors who no longer have the same type of high calorie and high protein needs that our younger cats do. Below, you’ll see a comparison chart that includes each product, their rating, and important information that can help you choose a great product for your elderly cat.

Cat Food for Older Cats Buyer’s Guide

As a cat ages, their dietary requirements will change. Proper nutrition can help to reduce your cat’s risk of heart disease, kidney disease, and cancer, in addition to developing certain chronic conditions such as diabetes or arthritis.

Like humans, a cat’s dietary needs will change as they grow older. Just like people, they need foods that can help aid in digestion and provide joint support. A cat will become less active in their old age, which will also reduce their daily caloric needs. Pet owners who aren’t aware of the senior’s special diet needs may continue to give their cat the kibble they’ve eaten for years, but this can lead to weight gain, heart disease, obesity, kidney failure, kidney stones, and chronic upset stomach.

Cat food for older cats is specifically designed to keep an older cat on the move and active. Products for seniors can include either dry or wet and products that are formulated for indoor pets, outdoor pets, and cats with sensitive stomachs or allergies.

Important Factors to Consider

senior cat eating cat food

When you’re shopping for food for older cats, pay attention to the product’s ingredients.

Many products will include high levels of taurine for eyesight support and heart health, in addition to vitamin E. Products that contain antioxidants can also be important since antioxidants can combat free radicals.

Avoid products that contain grains as the first, and main ingredient, products that are loaded with preservatives and additives, and artificial dyes. Cats with allergies may require a grain free formula.

Older cats may not eat as much as they did in their heyday, so every bite will count. Because of this, it’s important that you choose a food for older cats that’s loaded with essential nutrients.

Oral Health

Older cats can suffer from gum disease, tooth decay, muscle weakness, and other types of dental problems that can make chewing difficult. If you prefer to feed your cat kibble, then make sure the senior cat food features a kibble that’s small, so a cat won’t have to chew several times to break it down.

Canned can be easier for older cats with dental problems, especially if you choose a pate style texture. Other types such as minced, stews, chunks, or diced can also work well for cats with sore teeth and gums, as long as the meat is tender. With wet food, it can take a little firsthand research before you find a texture that your cat prefers.

Senior Cat Food for Indoor and Outdoor Cats

Both outdoor and indoor cats will share many of the same basic nutritional needs. However, an indoor cat tends to struggle more with digestive issues and hairballs. You’ll come across some senior cat foods that are specifically designed for indoor cats. This type of pet food will contain extra sources of fiber that will break up hairballs and make using the litter box easier.

They can also contain higher levels of vitamin E, which is also designed to prevent excess shedding and help reduce hairballs.

Moisture Requirement

Older cats are more prone to dehydration compared to young adults. They are also more prone to fatigue, which can decrease the likelihood that they’ll seek out fresh water.

Dehydration can be fatal to seniors. It can lead to liver failure, chronic constipation, and other health conditions. Because of this, ensuring your elderly cat remains well-hydrated is vital to their health. If you leave out a dish of water but you find that the water level in the dish doesn’t move much each day, then you should consider making the switch to wet food, which contains high moisture levels that can help to keep your pet hydrated. While canned is definitely not a replacement for water, it can help to minimize the severity of dehydration in older cats.

Higher Fiber

Older cats will have a hard time digesting certain types of protein, which is why a product with fiber is essential. Kibble that’s formulated for older cats will typically have a higher level of fiber compared to a formula that’s designed for adults. Kibble, not wet, tends to have the levels of fiber older cats need.

Low Fat

Cats slow down as they grow older. They’re not as active, may rarely play, and tend to spend most of their time napping. As their activity levels slow down, so does their digestive system. This will also have an impact on their digestive system’s ability to digest fats. This can put older cats at risk of obesity. Products that contain a lower fat content will help them to maintain a healthy weight, minimizing their chances of developing diabetes or heart disease.

Grain Free

If your cat has skin sensitivities or stomach issues, then they may have a grain allergy. Fortunately, there are many different types of grain free products available to choose from. If you’re not sure whether or not your cat would benefit from a grain free kibble, speak with their veterinarian. Making the switch to a grain free formula can provide immediate results, such as reduced episodes of constipation, vomiting, and diarrhea.

Serving Size

feeding an older cat

Many cat owners who have older cats may also wonder how much they should feed their cats and how often. The right portion size will usually depend on your pet’s current weight and what they’re eating. Caloric density in senior cat food tends to vary significantly from brand to brand. Cutting back by as little as an eighth of a cup can have a major impact on a cat’s weight. Portion control is very important at this age, since seniors are very prone to obesity due to their lack of activity. Instead of leaving a bowl of food out all day, feed your older cats two to three times a day, following the recommended portion size guide on the bag. Most manufacturers that produce cat foods for older cats will recommend a portion size based on a cat’s current weight and age.

When Should I Switch to Senior Cat Food?

There’s really no set age that a feline should be placed on  the best cat food for older cats. Ultimately, it will depend on each individual cat and what their vet recommends.

If a senior is maintaining muscle condition and body weight on their current diet, then there’s no reason they should switch to a diet designed for seniors. However, if they begin to gain weight, with no underlying health reason, other than their metabolism has changed, then feeding them cat food for older cats can help with weight management. If they’re losing weight due to a change in metabolism, they may even have to be placed on a diet for kittens, since it’s more calorically dense.

If a feline develops a health issue, such as diabetes, then switching to cat foods for older cats will be crucial.

Pet owners can discuss their cat’s changing dietary needs at their annual exam. When it’s time to make the switch to the right pet food, this should be done gradually, over a period of several days.

Transitioning slowly is done to prevent digestive upset and to ensure a cat accepts their new food.

Other Factors to Consider When Switching to the Best Cat Food for Older Cats

feeding senior cat food

When you’re choosing a new senior cat food, the main goals should be:

  • Reducing the symptoms of any pre-existing medical conditions
  • Preventing or slowing a chronic illness
  • Maintaining a healthy body weight
  • Additionally, the food’s moisture content, texture, and taste will also matter.


How a cat’s food tastes will become more important as their senses begin to wane as they grow older. In many cases, wet foods tend to rate higher with seniors, in terms of taste, due to the quality protein.

But this can also be dependent on each cat since some cats prefer wet food and others will prefer dry.

Many cats will develop a preference during adulthood. Since cats tend to be creatures of habit, if they’ve mostly eaten kibble over the years, they may not accept wet food. However, as I mentioned earlier, cats can also develop oral sensitivities and dental problems that can make eating kibble uncomfortable. If this is the case with your cat and he or she refuses to eat wet food, you can try adding water or diluted chicken broth to their kibble, to soften it up, making it easier for them to chew.

Food Texture

The best cat food should have a texture that’s palatable. An older cat with missing teeth may prefer wet or kibble that’s softened with broth or water. However, others will still prefer their standard crunchy kibble. A cat with missing teeth can still eat kibble because their gums will become harder. They may also still have other teeth they can use to crush the kibble.


As I mentioned earlier, older cats are more prone to dehydration as they get older, often because they tend to drink less water. Wet food has a higher moisture content. Additionally, food that has a higher moisture content may be more palatable to cats. Cats are carnivores that eat prey in the wild, which is why many prefer wet food since it mimics freshly caught prey. The higher moisture content in wet food can also help to reduce a cat’s risk of UTIs and other health conditions that are linked to dehydration.

The Picky Eater

Finding a senior cat food that has the right water content, texture, and taste, not to mention the right balance of nutrients, can be very challenging, especially if your senior is a very picky eater. If your cat is very finicky when it comes to what they will and won’t eat, the first question should be whether or not this is health related. Older cats are more prone to diseases, so an exam by your vet may be necessary if you find it increasingly difficult to find a senior cat food your feline will eat.

Benefits of Switching to Cat Food for Older Cats

old cat eating food

Seniors can develop some common health issues that can easily be managed by switching to the right diet.

  • If your cat is losing muscle, then they may need to make the switch to a higher protein senior cat food that also includes important vitamins and nutrients for aging felines. Sometimes, losing muscle is a direct result of certain diseases such as kidney disease, diabetes, or hyperthyroidism. Sometimes it can be caused by diet if their food was switched to a low protein formula. If your cat is disease-free, then they simply may require a low carb, higher protein diet.
  • If you have an overweight senior that needs to drop a few pounds, then a low calorie senior cat food can help them lose weight. A low calorie, low fat, high fiber diet can promote weight loss and fat mobilization.
  • If your senior is experiencing memory changes, such as forgetting where their litter box is, they’re displaying other types of senile-like behavior such as altered wake and sleep cycles or they’re wandering the house at night and meowing loudly, then a senior cat food that’s packed with healthy fats and antioxidants can help.
  • Sometimes not drinking or eating enough can be a major problem for seniors. The first step is to rule out any underlying health issues, and then make the switch to a flavor packed senior cat food. Additionally, warming up their food and offering several different flavors and textures of foods specifically designed for seniors can help to pique their appetite.

Frequently Asked Questions

What Should I Feed My Senior Cat?

A senior cat should be given wet food or kibble that contains the right level of protein and other nutrients, based on their specific needs. As an example, if your cat is overweight, then a low fat, low calorie food will be the best fit. Not all seniors will need special cat food as long as their bodies are still able to tolerate regular adult cat food.

Is Wet Food Better for Older Cats?

A wet senior cat food can encourage a cat that’s picky or a cat that’s losing their sense of taste, to eat. It’s also better for cats with dental problems or cats that don’t drink enough water, since wet food has a higher moisture content.

What to Feed an Older Cat that is Losing Weight?

If your cat is losing weight with no explanation, the first step is seeking medical attention. Unexplained weight loss can be caused by hyperthyroidism or cancer. If diet alone is to blame, then your cat may need food that’s higher in protein, calories and healthy fats.

Why is My Senior Cat Always Hungry?

One of the most common reasons a senior cat is constantly hungry is due to an overactive thyroid. Thyroid hormones are what are responsible for regulating the metabolic processes in the body. When a cat’s body produces too many of these hormones, it triggers an increase in their metabolic rate. Medical intervention will be required and is often very effective.

Do Senior Cats Eat Less?

As a cat ages, it’s normal for their eating habits to change. Some may lose interest in their old favorite food and others may simply not need to eat as much since they’re not as active as they were when they were younger. If there’s no underlying health condition to blame, try offering different flavors of cat food for older cats.

Can Cats Live on Dry Food Only?

Dry cat foods for older felines is perfectly fine, as long as the formula offers balanced and complete nutrition. Make sure you provide extra dishes of fresh water for your cat, since they will not get most of their hydration from kibble, like they can with wet.

Final Thoughts

When you’re shopping for the best cat food for older cats, stick to a premium brand that provides a formula that specifically targets seniors. These special cat foods for older felines are designed for older cats will contain the correct balance of essential vitamins, minerals, and nutrients that are needed to support a healthy lifestyle and reduce your cat’s risk of developing certain chronic conditions.
