If your cat is having an allergic reaction to their food, there are a few different ways to cope with their dietary needs. There are some hypoallergenic foods on the market (many of which are prescription cat food) that contain only hydrolized proteins. These are proteins broken apart so that the immune system cannot recognize them as a trigger for allergies.
Another method for feeding your allergy prone cat is to try different foods that will help you figure out what is causing the allergic reaction. Known as limited ingredient diets, these types of foods are a great option when combating a food allergy in your cat. Many brand name cat foods contain a mix of different types of proteins, grains, and other ingredients, any of which could be the cause of their mealtime woes.
Limited ingredient foods provide insight into what, specifically, is triggering your cat’s reaction by removing certain likely-suspect ingredients. Each one contains only a single source of protein, so for example, if your cat is allergic to beef, you would be able to tell, because the beef-only food would give them a reaction, whereas a fish or chicken-only type would not.
Here are some of the most popular hypoallergenic or limited ingredient cat foods:
