How do Food Allergies Affect Cats?
In cats, a food allergy or intolerance generally appears as gastrointestinal (GI) upset, leading to vomiting, diarrhea, excess gas or weight loss; or intense itching and scratching, which can involve the ears, face, feet, tail and stomach. Itching can result in red, irritated-looking skin.
Food allergy or intolerance can make both you and your cat miserable. So, it’s important to see your veterinarian as soon as possible if your pet experiences any of these symptoms.
