What Food Ingredients Are Cats Most Allergic To?

Cats can be allergic to nearly every cat food ingredient, according to Pet Education. An immediate negative reaction, such as vomiting, is not considered a food allergy; it is a food intolerance. An allergy is more likely to cause itching and skin problems.
