Why Is Nutrition Important to Cat Skin and Coat Health?

Nutrients such as protein, fat, vitamins, and minerals are important players in the skin and coat health of cats. To understand their role, it is necessary to start by understanding skin and hair. The purpose of skin and hair is to prevent things from leaving (such as water or heat) or entering (such as viruses and bacteria) the body.

A cat’s hair coat is composed almost entirely of protein. If a cat's diet doesn't contain adequate protein quantity and quality, hair may fall out or become dry, weak, and brittle.

Skin is made up of squamous cells, which are flat cells tightly packed together. These cells have tough membranes that are composed of proteins and fats. Without proper amounts of these nutrients, cell membranes weaken, allowing water to escape and bacteria and viruses to enter more easily.

Essential Amino Acids and Fatty Acids

Proteins are found in both animal-based and plant-based ingredients. Animal-based proteins contain all the essential amino acids cats need, whereas plant-based proteins may contain only some essential amino acids. Cats need animal-based proteins to achieve optimal health.

Fats can also be found in both animal-based and plant-based ingredients. They are incorporated into skin cells as fatty acids. There are two essential fatty acids for skin and coat health. Linoleic acid maintains skin and coat condition in cats. Without enough linoleic acid, cats may experience dull, dry coat, hair loss, greasy skin, and increased susceptibility to skin inflammation. Cats also require arachidonic acid for normal skin and coat health.

Both of these are omega-6 fatty acids and are found in animal tissues such as chicken fat and in vegetable oils (corn and soybean). However, most commercial cat diets contain more than adequate amounts of omega-6 fatty acids. Because these fatty acids can be converted to compounds that promote skin inflammation, it is important to balance the amount of omega-6 fatty acids in the diet with omega-3 fatty acids, which do not promote inflammation.

Omega-3 fatty acids are found in fish meal and some plants, such as flax.

Research by Eukanuba® nutritionists has found that combining fat sources in the diet in a ratio of five to 10 omega-6 fatty acids to one omega-3 fatty acid results in excellent skin and coat health.

Vitamins and Minerals

Vitamins and minerals are essential for the development of healthy skin and hair coat. The best way to provide these nutrients is through a complete and balanced diet containing appropriate amounts of essential vitamins and minerals rather than through supplements.

Changes in Coat Condition

Diet is often believed to be a factor when changes in skin and coat condition are noticed. The most common causes of these changes, however, are season and life stage. As cold weather approaches, most cats grow a thick coat to help keep heat in and cold air out. As the weather begins to warm up, they shed the thick, heavy coat.

Most kittens are born with soft, fuzzy hair, but as they age, a coarser coat grows. Pregnant or nursing cats also may experience a change in coat condition or hair loss.
