The affected area is most indicative of a flea saliva allergy. Although a food intolerance can cause itchiness anywhere on a cat's body, the face and bum is usually most affected. Our dermatologists tell us to apply an effective over the counter flea spot-on such as Advantage or a fipronil-containing product such as Frontline or one of the newer prescription products available from Scooter'svet even if fleas aren't seen. Cats can be such effective groomers so as to eliminate all evidence of flea infestation. Indoor cats can contract fleas because we walk them in on us and flea eggs and larva can remain viable in your home for months. Turning on the heater or as the weather warms at this time of year then hatches the eggs. Flea saliva allergy is usually most evident on the saddle area – the area between the edge of the rib cage and tail. In severe cases, an anti-allergenic prescription corticosteroid such as prednisolone will work wonders for cats allergic to the saliva of the flea. Your other cats may not be allergic to the saliva of the flea although fleas may have found them.
