Cats have allergies just like humans — and as with human allergies, cat allergies vary in severity and can only be managed, not cured. Cats can develop allergies from flea bites to food to airborne pollens. Reactions — often severe ones — may appear suddenly at any age. Some cats develop respiratory allergies (usually asthmatic wheezing) or digestive allergies (vomiting and diarrhea), but skin allergies are the most common.

A single cortisone shot from a general practice veterinarian or even an over-the-counter skin treatment can provide sufficient relief if symptoms are mild. But if basic treatments don't work or stop working, specialty intervention might be needed from a holistic practitioner or a dermatology/allergy specialist.

Also make sure your cat does not have an URI (upper respiratory infection). If it continues for a lengthy time, or seems to be worse, I would get him checked out by the vet.
