My cat has allergies and skin issues. What food helps avoid triggers?

Updated On September 23rd, 2025

Pet's info: Cat | American Shorthair | Female | spayed | 4 years and 1 month old | 10.4 lbs

Hello! My cat may have a food allergy which has made her lick and bite her skin resulting is big patches of hair loss. I've gone through the different foods she's been on and found that chicken by-product meal, animal fat, pork fat, and liver flavour are all used in the food, which I believe can be the culprit. What good quality food do you recommend without these, and that won't break the bank?

Thank you for submitting your question regarding Sage. Most over-the-counter foods are contaminated with ingredients not listed on the label. For example, if the diet lists the main ingredient as salmon, there could be small amounts of chicken in the food. This makes it very difficult if a patient has a food allergy. Prescription veterinary diets such as a hydrolyzed or a limited ingredient diet will be most successful for a food allergy. They are more expensive, but in the long run typically end up saving you money. If she is not constantly seeing her veterinarian for exams and medications due to skin disease, this will save you money. Hydrolyzed diets have the protein source chopped into such small pieces that the body's immune system does not recognize and react to it. Examples are Royal Canin Veterinary Diets Ultamino, Purina ProPlan Veterinary Diets HA or Hills ZD. The same companies make limited ingredient diets with one protein and one carbohydrate source. It can be some trial and error to find the best food. I hope this information helps!
