My cat has skin bumps. What food is best for her food allergy?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | spayed | 12 lbs

What is a good food to give my cat if a suspected food allergy. I’ve tried novelty protein, limited ingredient, cheap brands, expensive brands. She will eat an entire small bag of food and I’ll buy a larger bag and she may not eat that at all. I’ve gone through and wasted so many bags of food. She has small scans/bumps on her head and neck but I took her to the vet in October and he blood work was normal

There are several types of food allergy. If you have not had any luck with the brands you have tried, I recommend to try a prescription brand made by Royal Canin called Ultamino. The protein is broken down to the amino acid level, thus it will not trigger an immune response. Basically you need to feed this diet for 8 to 12 weeks. During this time she cannot eat anything else. No treats, no canned food, nothing. At the end of the 8 to 12 weeks, if her skin is all cleared up, then you know it is food. If her skin is not cleared up, then it is not likely food and you should look into other causes. I hope this helps and please feel free to post any additional questions!
