hopefully its just food allergies, they are much simpler to treat than inhalent allergies! but its hard to say, the symptoms are the same. glad you got him started on a food trial already. (although if it was a steroid injection he got, that will stop the itching and you wont be able to tell if its the food change thats helping him or the steroids..) well I hope he feels better soon anyway! and much luck in finding him a home!!!
