Nutrients such as protein, fat, vitamins, and minerals are important players in the skin and coat health of dogs and cats. To understand their role, it is necessary to first understand skin and hair.
The purpose of skin and hair is to block things (such as water or heat) from leaving, or things (such as viruses and bacteria) from entering the body.
The hair coat is composed almost entirely of protein. If an animal'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.
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 also can be found in both animal-based and plant-based ingredients, and 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 dogs and 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 essential fatty acids are omega-6 fatty acids and are found in animal tissues such as chicken fat. Linoleic acid is also found in some vegetable oils, such as corn and soybean oils. Most commercial cat diets contain more than adequate amounts of omega-6 fatty acids.
Because these fatty acids can be converted to compounds that increase susceptibility to 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 reduce susceptibility to inflammation.
Omega-3 fatty acids are found in oils from fish and some plants (canola and flax).
IAMS™ research has found that combining fat sources in the diet at 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 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.
| Vitamin or Mineral | Important for Skin and Coat Health |
|---|---|
| Vitamin A | Necessary for growth and repair of skin |
| Vitamin E | Protects skin cells from oxidant damage |
| Biotin | Aids in the utilization of protein |
| Riboflavin (B2) | Necessary for fat and protein metabolism |
| Zinc | Necessary for fat and protein metabolism |
| Copper | Involved in tissue, pigment, and protein synthesis |
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 dogs and 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 lactating cats also may experience a change in coat condition or hair loss.
If you are considering an all-natural, holistic, or organic kitten food, here are some facts you may not be aware of. Currently the pet food market is experiencing a push toward “all-natural,” “holistic,” and “organic,” the significance of which is still to be determined. The question becomes, is there an actual benefit to an “all-natural,” “holistic,” or “organic” diet?
AAFCO defines “natural” as “…derived solely from plant, animal, or mined sources… not containing any additives or processing aids that are chemically synthetic except in amounts as might occur unavoidably in good manufacturing practices.”
Loosely interpreted, this definition could include a range of “natural” products, including tobacco or any other naturally grown drug or substance.
None of these “all-natural” products are considered healthy additives for your kitten. So it is apparent that regulatory work is needed to define the true beneficial use of all-natural. Also noteworthy is the fact that nowhere within the definition are plant and animal by-products excluded. Not only are they “natural,” but they contribute valuable nutrients as ingredients in human and animal foods.
The term “holistic” kitten food is not distinctly defined by any of the regulatory agencies as a classification for food. This is particularly noteworthy in kitten food, because all diets sold commercially must be “Complete and Balanced” for a designated age or activity level. Or in other words, be a “holistic” dietary approach.
Organic kitten food is labeled “organic” by a government-approved certifier who inspects the farm where the food is grown to make sure the farmer is following all the rules necessary to meet USDA organic standards. Whether organic kitten food provides any additional safety or nutritional value is still being debated by experts. Even the USDA refuses to take a position. It is also important to note that there are no strict requirements for organic kitten food right now.
There is tremendous confusion surrounding the significance of all-natural, holistic, and organic kitten food terms. Widespread use without substantiation has forced several government and “watch-dog” consumer groups to become involved; this will result in more education and clarification as to what these terms really mean to consumers. But, for now usage of these terms requires your consideration.
