Humans aren’t the only ones affected by allergies. Like you, your adult cat can suffer from allergic reactions to any number of things in the air, on her skin and in her food. Allergies must be diagnosed and treated by a veterinarian, but first you must know what to look for.
Four of the most common types of allergies that might affect your cat are inhalant, food, contact and flea allergies.
Inhalant allergies in cats are caused by the same common allergens that affect you: dust, grass, trees, mold, pollen, ragweed and so on. They can be seasonal or persistent, and while some breeds may experience the same sniffly, sneezy symptoms humans often suffer, skin reactions are most common. Inhalant allergies can often be treated with the same medications you take, but please don’t treat your cat’s allergies without veterinary supervision.
Food allergies in cats can be the most difficult to diagnose and manage. Treatment involves a hit-or-miss approach involving a restricted diet and the gradual reintroduction of possible allergens to determine the culprit. Skin reactions to food allergies are common in cats, but frequent vomiting or diarrhea also can be a sign. Keep in mind that if your cat’s diet changes (or she just ate something she wasn’t supposed to), she may experience an episode of vomiting or diarrhea. This doesn’t necessarily mean your cat has an allergy. Watch and see if it becomes a persistent problem before scheduling a trip to the vet.
You might be surprised to learn that most cats are only vaguely bothered by fleas. But those that are allergic can suffer — and so can their owners. Contact and flea allergies generally cause skin irritation in cats and are treated topically. Cats with contact and flea allergies often chew their skin raw, leading to hair loss, odor and infection, so fastidious flea control is a must.
The most common allergy symptoms in cats are skin reactions, regardless of the cause, and they can appear at any age. Just because your cat didn’t have allergies as a kitten doesn’t mean she won’t have them as an adult. If your cat suffers from any of the following symptoms, take her to the vet for a consultation:
Allergies can vary from cat to cat, so it is important that you work with your vet to make sure your cat gets the best possible treatment. You’ll both be happier as a result.
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.
