The Nutritional Needs of an Older Cat

Cats live longer, healthier lives than they used to, with better nutrition and preventative veterinary care contributing to your cat’s life longevity. 

Like us, cats endure different stages within their lifetime. The following life stages have been identified and categorized by the American Association of Feline Practitioners (AAFP):

  • Kitten: Birth up to 1 year
  • Young adult: 1 to 6 years
  • Mature adult: 7 to 10 years
  • Senior: 10 years and older

Your cat’s nutritional requirements will alter several times during its life due to the physical differences that come with aging. Their diet may need adjusting to cater to these changes so that they can enjoy a healthy lifestyle. 

An incredible 35-40 percent of cats in the United States are over the age of seven. When cats become mature adults, they can often gain weight as calorie requirements decrease. However, once they enter the senior phase, their energy requirements increase due to a reduced ability to digest protein and fat. These changes can result in weight loss.

It is essential to recognize when your cat’s body and muscle condition is changing. Preventative care and proper nutrition can help your senior cat maintain a healthy weight and muscle. It can also alleviate the risk of health issues such as osteoarthritis, cancer, and kidney disease.

Calorie Consumption

We regularly need to decrease a mature cat’s calorie intake to prevent excessive weight gain as they get older. However, a senior cat usually needs increased calories to maintain a healthy weight and lean muscle mass.

Portion control is vital when it comes to feeding your senior cat. Cat food does come with feeding instructions, but these don’t suit every cats’ needs. Consult your veterinarian if you need help adjusting your cat’s feeding regime.

What is Senior Cat Food?

The Association of American Feed Control Officials (AAFCO) defines the nutritional requirements for kittens and adult cats. There are no dietary profiles for older cats, and there isn’t much difference between adult and senior cat food. The main difference is that senior foods usually contain slightly more fiber to aid digestion.

Therefore, if your cat is doing well on its usual diet, there is no reason for you to switch foods.

Changing your cat’s diet is dependant on each feline. Some senior cats will have health issues that may require a specialized diet, not just senior cat food. Health problems such as kidney disease, allergies, hyperthyroidism, and heart disease are among the issues that may require a diet change.

If your cat isn’t suffering from any health problems, keep a close eye out for physical changes like:

  • Age: The most apparent sign is age. Many cats will need a change in diet at around seven years old and again at approximately 11 years old. This is because of a change in metabolic rate and the need for extra fiber to aid digestion.
  • Dull coat and flakey skin: If your cat’s skin becomes irritable and isn’t caused by allergies, your cat’s food may not provide enough fatty acids. Senior foods usually should contain more fats that help maintain skin and coat and aid joint health.
  • Weight loss or gain: A decrease in weight may indicate that your cat’s regular diet isn’t providing them with enough calories anymore. In comparison, if your cat is putting on weight, they may need low energy, high fiber diet.

Always consult your veterinarian if you’re considering changing your cat’s diet. 

Is Dry or Wet Cat Food Better for Older Cats?

As cats get older, their teeth and gums may find wet food easier to manage. Wet cat food consists of more animal proteins and fats suited to a felines’ natural diet. There are also fewer carbohydrates in wet cat food, which is excellent as carbs are difficult to digest.

Canned food is full of hydration, whereas dry food contains very little moisture, which can lead to dehydration. Moisture content is crucial for cats as they tend not to drink a lot of water.  

Dehydration increases the risk of cats developing urinary tract infections and kidney problems. If you feed your cat on dry cat food, add water to their meal or supplement their diet with wet food. 

Not only does wet food provide your cat with more moisture, but it also makes mealtimes more enjoyable. It generally tastes and smells better for your feline. 

Another reason it may be better to feed your older cat a canned cat food is if they are suffering from dental problems. 

Several dental diseases are common in cats, including gingivitis and periodontitis. These diseases can cause extreme pain and discomfort, and your cat may be reluctant to eat or eat food in a strange way. Cat foods with a pate texture are excellent in situations such as this.

Although wet cat food seems far more beneficial than dry cat food, it is more expensive and harder to maintain. Dry cat foods are generally cheaper and fantastic at supporting oral health. However, it’s higher in carbohydrates, leading to an increased risk of health problems such as diabetes and obesity.

Feeding your cat a combination of wet cat food and dry cat food allows you to give them the benefits of both worlds. It also leaves your pocket feeling a little happier.

The AAFCO Statement

AAFCO aims to protect consumers by providing nutritional, labeling, and ingredient requirements for manufacturers to follow. Check the packaging for the AAFCO nutritional adequacy statement, so you know that your cat’s meal is nutritionally complete and balanced.

AAFCO test the food or complete a formula check to confirm the pet food is nutritionally adequate. A feeding test requires the food to be tested on live animals to check digestibility and nutrient absorption. A formula check compares the nutritional analysis of the ingredients against the AAFCO nutritional profiles.

Manufacturers will label their foods according to the life stage it’s aimed at, and the calorie content will differ between them. However, although AAFCO has nutrient profiles for kitten and adult cat maintenance, they fail to mention senior cats. Therefore, nutrient profiles can vary dramatically.

Quality Protein 

Cats are obligate carnivores, meaning they need animal-based protein in their diet. Felines can’t synthesize amino acids such as taurine and arginine; they need to obtain them from meat. Cats also need these essential vitamins such as niacin, vitamin A, and vitamin D from the meat in their diet. 

Look for sources such as chicken and beef rather than meat by-products.

Meat by-products can contain animal organs, bone, blood, and fatty tissues. These are non-rendered and used as a cheap alternative source.

You may also come across meat meals. These are rendered and dried before being added to pet foods, and they can be an excellent source of concentrated protein.

Protein Content

The AAFCO recommends a minimum of 26 percent protein on a dry matter basis for adult cat maintenance. However, studies have shown that cats consistently fed less than 40 percent protein lose lean muscle mass over time. 

Older cats aged 12 years and over require more protein in their diet. Unfortunately, due to common health risks such as kidney disease, many diets for older cats contain reduced content. Unless your cat has been recommended a protein-restricted diet, there is no need to reduce it.

The nutritional analysis on pet food packaging is printed on an ‘as fed’ basis. AAFCOs nutritional profiles are on a dry matter basis; this means water isn’t taken into account. 

Dry matter calculators like this one help calculate the macronutrients such as protein, fats, and carbohydrates in your cat’s diet.

Highly Digestible Ingredients

As cats get older, they become less efficient at digesting food. To help them cope with this decline in efficiency, check that their diet is full of easily digestible ingredients. Cats find meat proteins much easier to digest than grains. Make sure the first ingredient in your cat’s food is a meat source.

High Moisture Content

Water is the most important nutrient in your cat’s diet. As discussed earlier in this article, cats don’t drink a lot, so it’s crucial to aid hydration. You can assist water intake by providing wet cat food or adding water to dry cat food. You could also encourage your cat to drink by giving access to a drinking fountain as they usually prefer running water.

Sufficient Calories

Underweight senior cats will require a calorie-dense formula. Veterinarians occasionally recommend kitten food to senior cats that are severely underweight due to its high calorie and fat content.

Cats that are overweight will need a restricted-calorie diet that’s high in fiber and low in fat. This diet needs to be combined with a strict feeding schedule and portion control.


Cats can’t synthesize essential fatty acids, so they need to obtain them from food. Dietary fats are derived from animals, plants, and seed oils. They contain essential fatty acids that keep your cat’s skin and coat, provide energy, and aid the absorption of fat-soluble vitamins.

They can also reduce inflammation which can alleviate joint pain, and clinically benefit heart and kidney disease.


Cats require several minerals in their diet; calcium, chlorine, copper, iodine, iron, manganese, magnesium, phosphorus, potassium, selenium, sodium, and zinc. If a cat food carries the AAFCO statement, these minerals should be present in the recommended amounts.

Low Phosphorus Levels

Older cats are at a higher risk of kidney problems, and phosphorus can exacerbate symptoms. Although senior cats need phosphorus in their diet, excess phosphorus in the bloodstream can cause other health issues. Some senior cat foods will contain restricted phosphorus levels to avoid overworking your older cat’s kidneys.

Can I Suddenly Change My Cats Food?

Changing your cat’s food should be done gradually over a minimum of one week. Slowly transitioning your cat’s diet helps to avoid gastrointestinal upset. Check out these general guidelines for switching foods by the Veterinary Medical Center at Tufts University.

How Often Should I Feed My Senior Cat

It’s been suggested that you split your cat’s daily food portion into at least two meals. Some older cats don’t like to be overwhelmed with large amounts of food, and they may require feeding little and often. It’s okay to provide your cat with more meals throughout the day but stick to the daily food intake recommended by your vet.

Do Senior Cats Need Less Protein?

The most critical nutrient in a cat’s diet, after water, is protein. Dr. Karen Becker, DVM, an expert in feline nutrition, states that senior cats need more protein than kittens. 

Veterinarians often recommended low protein diets for cats with kidney disease as they thought high protein posed a risk to kidney function. However, protein is no longer considered the issue; they now believe phosphorus levels are responsible for causing kidney damage.

Should I Give My Cat Vitamins and Supplements?

If you’re feeding your cat a nutritionally complete and balanced diet, there should be no need to provide vitamins and supplements. If you think your cat may need supplements, consult your veterinarian. Feeding your cat with excessive vitamins can be dangerous.
