Thanks everyone. I just found out the Petsmart carries a very good allergen food called Natural Balance Venison & Green Pea Allergy Formula For Cats. I think I'm going to try this for about a week before I call my vet. I really don't want to have to put Starr on steroids either because this will compromise his immune system which is already a weak one. Here's the link:Natural Balance Venison & Green Pea Allergy Formula. I'll let you know how it goes. Thanks again.
