My cat is vomiting and licking fur after new food. Is it an allergy?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Male | neutered | 9 years old | 12 lbs

I changed my cats food to Wholehearted grain free easy digestion chicken/egg flavor. He is licking his fur off in spots since I changed it and he vomits frequently. Could he be allergic to something in this food? It seems like it should be a good choice for him.

It's definitely possible that Buddy is allergic to his food as one of the most common food allergies is to chicken. You may want to try a diet with single source or protein that is something Budddy has never had before (like venison or rabbit). An all canned food diet is also preferred and may help with a potential food allergy. One over the counter option is Natural Balance Limited ingredient diet. It would also be a good idea to have Buddy examined by a veterinarian to ensure he does not need medication to treat the itching or vomiting. There are many other causes of these signs so it's important to rule those out first. Your veterinarian can also prescribe a special diet that may work better (like Royal Canin Ultamino) if food allergies are truly at play. Thanks for using Petco Pet Education Center, formerly Petcoach and I hope Buddy's issues resolve quickly!
