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 to humans, your cat needs a high-fat, high-protein diet along with other important 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 with Chicken, are best suited for free choice feeding because they stay fresh for a longer period.

Cats need nutrients from animal-based protein sources. Providing the vitamins, minerals, proteins, and other components found in a portion of complete and balanced pet food can help your cat live a long and healthy life. It is important to avoid supplementing your cat's diet, as doing so may lead to a variety of health problems.
When selecting cat food, look for ones that offer the following nutrients:

A cat's energy intake should be increased gradually by up to 50% over her maintenance intake throughout its pregnancy. You can feed your pregnant cat wholesome kitten food to provide the needed nutritional support during the last few weeks of gestation.
After birth, the mother cat's energy increases by 50% to 75% over normal in the first week to twice the normal in the second week, and up to three times during the third week. The third and fourth weeks are the most demanding because kittens are still feeding on the lactating cat’s milk and have not begun eating dry or canned food. Once kittens begin weaning, the mother cat should be feed normal food portions to avoid unnecessary weight gain.

‘What do cats eat that result in them developing obesity’ is a commonly asked question by cat parents. Several factors are responsible for causing an unhealthy weight gain in your cat. Food and nutritional requirements of a cat are quite different than that of a kitten or even a senior cat. Simply increasing the amount of food your cat eats to satisfy its nutritional need could lead to cat obesity. And this is a health problem that should not be taken lightly. In general, indoor cats are at a higher risk of developing obesity because they do not engage in many physical activities. But as a cat parent, you must pay attention to your cat’s food intake and make sure it remains active. You may also introduce a new kind of diet that may help your cat to maintain its weight. Read further ahead for some useful cat feeding tips that can help you.

same time, we recommend you control the amount of food you feed your cat. Even if it is a weight loss-based cat food, the quantity should be checked properly.
Cats spend a considerable amount of time grooming themselves. In the process, they end up swallowing their body hair. This leads to a hair build-up in the stomach. If the hairball doesn’t pass into the intestines, a cat may try to cough it up. A special diet can help decrease the likelihood of hairballs, but you may decrease its effectiveness if you combine it with other foods.
Underweight cats need more nourishment, which will help them increase their body mass, eventually increasing their weight. For underweight cats, an intake of extra calories is also essential. These extra calories will help your cat gain healthy weight. You may contact your vet who can devise a proper weight gain chart for your cat.
Overweight cats need a calorie-restricted diet for them to come down to their healthy weight. In fact, the food you feed your overweight or obese cat should ideally have high protein and low calories. At the
The amount to feed your cat depends on its age, size, and activity level. Feeding guidelines that recommend the daily amount of food you may feed your cat are included on all IAMS packages. Start feeding your cat the mentioned amount and adjust according to its needs. Remember to divide the portion accordingly if you feed more than once a day. With that said now, take a look at this table to know how much to feed your cat:
