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.
Are you considering feeding a raw diet to your kitten? Before you do, make sure you have the right information. Get the facts about 10 common myths associated with raw meat diets.
FACT: No scientific studies have shown benefits of feeding raw diets to kittens or cats. Their appeal is based on word of mouth, testimonials and perceived benefits.
FACT: Lynxes and other animals in the wild, like wolves, do eat raw meat (in addition to berries, plants, etc.). However, the average lifespan for an animal in the wild is only a few years. Therefore, what is nutritionally “optimal” for a wild animal like a lynx is not optimal for our pets that we hope will live longer and healthier lives.
FACT: Cats, especially kittens, senior cats or immunosuppressed animals, can become infected with Salmonella, Clostridium, Campylobacter and other bacteria found in raw meat diets, just as people can.
FACT: Even meats purchased at the best stores for people can contain harmful bacteria, so purchasing “human-grade” meat does not protect against the health risks of uncooked meats. (Ask yourself: Would you eat raw ground beef?) It is also important to keep in mind that the term “human grade” has no legal definition for pet food.
FACT: Most of the bacteria found in raw meat diets can easily survive freezing and freeze-drying.
FACT: Bones, whether raw or cooked, can fracture your kitten’s teeth. They also can block or tear the esophagus, stomach or intestine.
FACT: All the enzymes dogs and cats (and people) need for digestion are already in the gastrointestinal tract. Additional enzymes from food are not required for digestion.
FACT: Corn, oats, rice, barley and other grains are healthy ingredients that contain protein, vitamins and minerals; they are not added as fillers and are unlikely to cause allergies. Although meat is an important component of diets for kittens and cats, grains can be part of a high-quality, nutritionally balanced diet.
FACT: Byproducts are the animal parts American people don’t typically eat, such as livers, kidneys or lungs — in other words, the organs and meats other than animal muscle. Note that some pet foods may actually list these ingredients (e.g., duck liver, beef lung), but these are really just byproducts. Most commercial and many home-prepared raw diets also contain by products.
FACT: Most homemade (and even some commercial) raw meat diets are extremely deficient in calcium and a variety of other nutrients, even if chicken necks, bones or eggshells are added. This can be disastrous for any animal but especially for young, growing kittens, and can result in fractured bones. For complete and balanced nutrition, feed your cat a high-quality kitten food like IAMS™ ProActive Health™ Healthy Kitten.
