Best High Protein Cat Food

Protein is important for all animals. It is needed for growth and development and for the immune system. It helps repair cells and make new ones. It is part of the structure of every cell. Protein, made from amino acids, helps create our bodies, and grow skin, nails, and hair. Protein can also be burned as calories or converted and stored as fat if your body has extra protein.

Cats need 22 amino acids (the body uses amino acids to make proteins). Cats can synthesize 11 of these amino acids in their own bodies – this is not unusual. Most species can make some of the amino acids they require. The remaining amino acids – the ones they can’t make themselves – are called “essential” amino acids. Your cat has to get these amino acids in his diet. If your cat is deficient in any of these amino acids, such as taurine or arginine, it can lead to health problems.

What happens if a cat doesn’t get enough protein?

If a cat doesn’t get enough protein he can start to break down protein from his own muscles, so it’s important that cats do get a high enough level of protein in their diets.

Every source of protein, including meat proteins and plant sources of proteins, has different amino acids. Some are easier for a cat to break down and some are more (or less) usable for your cat. Scientists call a protein’s ability to be broken down and used its “bioavailability.” The egg is considered to be the most food with a bioavailable value of 100. Milk and fish meal have bioavailable values of 92. Beef has a value of about 78. All of these foods can have lots of protein available but that doesn’t always mean they are the best choice to feed a cat for other reasons. Most people don’t choose to feed their cat a cat food that is primarily made from eggs, for example (though some cat foods do use eggs in the ingredients). You always have to consider other factors when you are choosing a diet for your cat.

Most people don’t have to worry about feeding their cat too much protein. If you feed your cat a diet that has more protein than he needs, he will excrete the excess in his urine. Or use some of the protein as calories or store some as fat. The only time a very high protein diet might be a problem is if your cat has late stage kidney disease – and recent studies are suggesting that a high protein diet made from the very best protein sources would still be beneficial for such cats because they would give the kidneys little waste to remove from the cat’s body.

It’s not always easy to know the amount of digestible protein in a cat food. It’s easier to discover this information if you can look at the entire nutrient profile for a cat food, but most cat food companies don’t provide them even on their web sites. Just looking at the percentage of protein in the food from the guaranteed analysis won’t tell you how easy the protein is for your cat to digest. However, most better quality cat foods will usually have better quality ingredients that are easier for your cat to digest. Note that we say “usually.” You can always be fooled. Some meat proteins are easier for most cats to digest, such as chicken, fish, beef, and lamb. Lower quality foods may use lower quality sources of protein that can contain feathers, hair, etc. You don’t have to buy the most expensive cat food on the shelf, but better quality cat foods usually contain better quality ingredients, so you probably need to buy something mid-priced or above to get good quality ingredients for your cat. At the same time, we don’t like to see people buy over-priced, over-hyped foods, and some of the most expensive brands are not really better than the mid-range foods.

Advantages of a high protein diet

There are many advantages of feeding a high protein cat food to your cat. Many cat experts and veterinary nutritionists agree that cats have a need for more protein in their diet than dogs, for example. And you can find plenty of articles and references online that attest to the fact that cats are obligate carnivores, and thus they need meat in their diet. They don’t have salivary amylase to help break down starches; and they don’t have the enzymes needed to help digest carbs in their gastrointestinal tract. Unlike dogs, which have evolved genes to help digest starch since they separated from wolves, cats don’t have the same capacity. Animal protein in a cat’s diet is also a good way to help ensure they get some of the essential amino acids they require.

Cats prefer higher protein

Left to their own devices, cats will overwhelmingly choose a higher protein food. A study reported in the Huffington Post by Dr. Karen Becker found:

  • Given the option, the cats exclusively chose high-protein food over high-carb food even when there was less of the high-protein food available.
  • Cats offered a choice of three foods with variable amounts of protein, carbs and fat mixed them to achieve a daily intake as follows:
    • 100 calories or 52 percent from protein
    • 67 calories or 35 percent from fats
    • 24 calories or 12.5 percent from carbs
  • When the cats were restricted to a high-carbohydrate food, they did not eat enough of it to get the targeted amount of protein (52 percent).
  • Experienced cats eating dry food increased their protein intake and ate fewer carbohydrates than naïve cats offered the same choices. This indicates that given the option, cats learn to avoid eating excessive amounts of carbs.

Interestingly, the nutritional content of an adult mouse is said to be 55.8 percent protein and 23.6 percent fat, so perhaps this provides some insight on how much animal protein cats prefer in their diet. It seems very close to the amount (52 percent) found in the study above.

According to one source, this is what a cat might eat in the wild:

Remember that cats as obligate carnivores need proportionally more protein in its diet compared to other mammals (1-3). Cats do not have a dietary requirement for carbohydrates. Therefore, cats are adapted to eat a protein-rich, carbohydrate-poor diet. The composition of a cat’s diet in the wild (as a percentage of calories or metabolizable energy ingested) is approximately 50-60% protein, 30-50% fat, and 5-10% carbohydrates (2,11-13).

So, if we are agreed that your cat can benefit from eating a high protein cat food, what do you need to look for in one?

High protein cat food diets

AAFCO and other sources today recommend that adult cats have a minimum of 26 percent protein in their diet. Kittens (and pregnant and lactating queens) should have a minimum of 30 percent protein in their diets. These figures are based on dry matter comparisons. Table 4

There are no maximums percentages provided. Note that these are minimums, not the optimum percentages. Cats with specific health issues or elderly cats will need to have these percentages adjusted. Many cats will benefit from eating a diet that is higher in protein, with lower carbs.

The source of the protein is very important in any food you choose for your cat since cats can usually digest meat sources of protein better than plant sources. This means they will obtain more nutrients from the meat source-protein and pass less of the food as waste. It’s really true that if you feed your cat a better quality cat food you can feed less food and pick up less cat poop because your cat is digesting the food more efficiently.
