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.
Compared with humans, your favorite feline needs a high-fat, high-protein diet with certain animal nutrients.
Cats usually eat many small meals throughout the day, so they easily adopt a free-choice feeding schedule to maintain their normal body weight. Dry foods, such as IAMS™ Proactive Health™ Healthy Adult - Chicken, are best suited for free-choice feeding because they stay fresh longer.
Cats need nutrients from animal-based protein sources. Providing the vitamins, minerals, protein, and other components found in a complete and balanced pet food can lead to a long and healthy life for your cat. It is important to avoid supplementing your cat's diet, as doing so may lead to a variety of health problems. When selecting a pet food, look for ones that offer the following nutrients:
Animal protein from meat, poultry, fish, or egg sources to maintain strong muscular structure, vital organs, antibodies, and more
Taurine, an amino acid found in meat sources such as chicken and fish, but not in plant proteins, to maintain healthy eyes, prevent heart disease, and promote healthy reproduction, fetal growth, and development
Essential vitamins and minerals such as vitamin A, which can be found pre-formed only in animal tissues, and vitamin E to help support the immune system
A precise balance of fatty acids to help promote excellent skin and coat health
A fiber source, such as beet pulp, that will help maintain your cat's digestive system health.
Pregnant or Lactating Cats
A cat's energy intake should be increased gradually by up to 50% over her maintenance intake through pregnancy. You can use kitten food to provide nutritional support during the last few weeks of gestation.
After birth, the mother cat's energy needs increase by 50% to 75% over normal in the first week to twice normal the second week and to three times during the third week. The third and fourth weeks are the most demanding because kittens are still consuming milk and have not begun to eat dry food. Once kittens begin weaning, the mother cat should be tapered back to normal food portions to avoid unnecessary weight gain.
Avoiding Obesity
Food and energy requirements may vary for your adult cat. In general, indoor cats have less opportunity or need to exercise than outdoor cats. As a result, indoor cats are more prone to obesity, and regular exercise should be encouraged. You may want to control your cat's portions.
