Cats are obligate carnivores, meaning they require a diet rich in animal-based proteins. Animal proteins contain all the essential amino acids that cats need to consume through their diet, as their bodies cannot produce enough of them on their own. While cats can eat some plant-based proteins, these should not be their primary source. A cat's diet should include approximately 26% protein, with some sources suggesting a minimum of 30% for optimal health. As cats age, their protein requirements increase, with some sources recommending a diet of nearly 50% protein for senior cats.
| Characteristics | Values |
|---|---|
| How much protein should be in a cat's diet? | The general consensus is that protein should make up about 26% of an adult cat's diet. However, some sources suggest that a minimum of 30% protein is required for "Growth and Reproduction" life stages, and 40% for adult cats to maintain lean body mass. Cats over 12 years old may need a diet of nearly 50% protein. |
| What are the best sources of protein for cats? | Animal-based proteins are the best source of protein for cats, as they have complete amino acid profiles. Cats are obligate carnivores, meaning they need to eat meat. Sources of animal protein include beef, pork, lamb, and fish. |
| What are the dangers of a low-protein diet for cats? | A diet that does not contain enough protein can lead to muscle loss and serious diseases such as heart disease. |
| How does protein content vary between dry and canned cat food? | Dry cat food tends to have lower protein content and is often made up mainly of plant proteins rather than meat proteins. Canned food is recommended by some veterinarians as it has a higher water content and lower carbohydrate load. |
| How do I determine the right amount of protein for my cat? | Work with your veterinarian to determine your cat's caloric requirements and select a suitable food. |

Cats are obligate carnivores, meaning they need meat-based protein
Cats are obligate carnivores, which means their bodies are designed to eat meat. They require a diet rich in animal-based proteins, as these contain all the amino acids that a cat needs. Animal proteins are considered complete proteins, whereas proteins from other sources, such as vegetables, cereals, and soy, are incomplete as they do not contain all the essential amino acids.
A cat's body does not produce enough amino acids on its own, so it is important that they obtain these from their diet. Amino acids are the building blocks of proteins and are essential for growth, maintenance, reproduction, and repair. There are 23 amino acids that make up the mammalian body, and cats can only produce 12 of these themselves, so the remaining 11 must be obtained from food. These are called essential amino acids and include arginine, methionine, histidine, phenylalanine, isoleucine, threonine, leucine, tryptophan, lysine, valine, and taurine.
Taurine, in particular, is an amino acid that is important for normal heart function, vision, and reproduction in cats. Since taurine is found only in animal-based proteins, a meat-based diet is crucial for cats to meet their nutritional requirements. A deficiency in taurine, for example, can cause serious heart disease.
The general consensus among feline nutrition experts is that a cat's diet can include small amounts of plant-based foods, as wild cats also consume the stomach contents of their prey, which may include plant matter. However, grains and starchy vegetables should be kept to a minimum, if included at all. The National Research Council's Subcommittee on Cat Nutrition states that there is no known dietary carbohydrate requirement for cats.
The amount of protein in a cat's diet is also important. AAFCO guidelines recommend a minimum of 30% protein for growth and reproduction and 26% for adult maintenance. However, recent studies have shown that adult cats that did not consume at least 40% protein lost lean body mass over time. As cats age, their protein requirements increase due to a reduction in digestive efficiency, and cats over 12 years old may need a diet consisting of nearly 50% protein.
In addition to protein, a cat's diet should also include other nutrients such as water, vitamins, and minerals, as well as fat and carbohydrates as energy sources. It is important to provide cats with a balanced diet that meets their nutritional needs.

AAFCO recommends a minimum of 30% protein for growing cats and 26% for adults
Cats have a high requirement for protein in their diet. Protein is a critical nutrient to consider when planning a diet for cats, as they are obligate carnivores. The Association of American Feed Control Officials (AAFCO) regulates the sale, distribution, and nutritional requirements for pet food. AAFCO-compliant food adheres to nutrient profiles that include recommended amounts of amino acids such as taurine and arginine.
AAFCO guidelines recommend a minimum of 30% protein for "Growth and Reproduction" life stages and 26% protein for adult maintenance. These minimums are established by feeding eight cats these nutrient minimums for 26 weeks and conducting health evaluations. It is important to note that AAFCO is not claiming that 30% protein is optimal for kitten growth, but rather that it is the bare minimum to maintain the kitten's growth and health.
Recent studies have shown that adult cats that did not consume a diet of at least 40% protein lost lean body mass over time. As cats age, their protein requirements increase due to a reduction in digestive efficiency, and many cats over 12 years old should be fed a diet containing nearly 50% protein.
It is worth noting that cats respond differently to various foods, and it is important to work with your veterinarian to determine your cat's specific caloric and nutritional requirements.

Cats over 12 may need a diet of nearly 50% animal protein
Cats are obligate carnivores, meaning they require a diet rich in animal-based proteins. While dogs can be omnivores, cats are strict carnivores and require significantly more protein. Cats get their protein from meat, and their diet should include animal-based proteins with complete amino acid profiles.
A cat's diet should include nutrition requirements such as water, vitamins, minerals, protein, fat, and carbohydrates. Protein should make up about 26% of an adult cat's diet. However, as cats age, their protein requirements increase due to a reduction in digestive efficiency. Cats over 12 years old may need a diet of nearly 50% animal protein to prevent muscle loss.
The type of protein is also important. Animal-based proteins are more expensive but are much easier for cats to digest than plant-based proteins. They are also more suitable for the feline digestive system. While it is fine to give your cat treats, they should make up no more than 5% of its daily nutrient intake. The rest of its diet should come from a high-quality kitten or cat food.
It is important to work with your veterinarian to determine your cat's specific caloric and nutritional requirements. They can help you select a suitable food and calculate how much to feed your cat.

Cats require more protein than dogs
Taurine, in particular, is an amino acid that is important for normal heart function, vision, and reproduction in cats. Since taurine is found only in animal-based protein, all cats need meat-based diets to meet their nutritional requirements. A deficiency in taurine can cause serious heart disease.
The general consensus among feline nutrition experts is that while small amounts of plant-based proteins are okay, a cat's diet should not primarily consist of these. Cats are able to obtain plant-based proteins from the stomach contents of their prey, but grains like corn should not be at the top of the ingredients list. AAFCO guidelines recommend a minimum of 30% protein for "Growth and Reproduction" life stages and 26% protein for adult maintenance. However, an even higher percentage of dietary protein is likely warranted for optimal health.
Cats over the age of 12 may need as much as 50% of their food to consist of animal protein. High-protein diets are also recommended for older cats to prevent muscle loss. It is important to note that not all animal-based proteins are equal, and some sources may be more beneficial than others. For example, while cats can eat just about any fish, it is best served as an occasional treat rather than a primary source of protein due to its high sodium content.

Cats need a balanced diet with vitamins, minerals, fat and carbohydrates
Cats are obligate carnivores, meaning they require meat in their diet. They have a high protein requirement, and animal-based proteins have complete amino acid profiles. In addition to protein, cats need a balanced diet with vitamins, minerals, fat, and some carbohydrates.
Vitamins are organic compounds that are necessary for cats in small amounts. For example, vitamin A is crucial for a strong immune system and healthy vision, but too much vitamin A can be toxic to cats. Similarly, vitamin D aids in the functioning of bones, nerves, and muscles but should not be consumed in excess. Cats also require vitamin B1 for the healthy metabolism of carbohydrates and maintenance of normal growth, and vitamin B6 for immune function and red blood cell function.
Minerals are inorganic compounds that are required in a cat's diet for normal body functions. Some essential minerals for cats include calcium for bone growth and formation, magnesium for enzyme function and metabolism, iron for oxygen transport, copper for iron absorption and skin pigmentation, manganese for metabolism and immune function, and zinc for metabolism.
Fat is another important component of a cat's diet, as it provides energy and aids in the absorption of fat-soluble vitamins like vitamins A and D. While carbohydrates are not a necessary dietary requirement for cats, they can provide a small amount of energy. However, a diet high in carbohydrates is not natural for cats and may lead to weight gain and health issues like diabetes.
Overall, it is important to provide cats with a balanced diet that includes various nutrients such as vitamins, minerals, fat, and carbohydrates, in addition to their high protein requirements.
