Q. my cat is scratching her ears to the point she's loosing hair in that area.I used Frontier,as she has no fleas,please help
DR. MASSIMO ORIOLES, DVM, MRCVS
A. Ear inflammation/infections are still possible. Possible causes are ear mites, ear polyps for example or more generalized causes of pruritus such as allergies, more severe flea infestations (some products sometimes are not ''enough'' to treat fleas) and many others.
I would recommend to take her to your veterinarian for a check up as otoscopic examination and further treatment are needed to understand the underlying cause.
