Thank you very much. This is kind of what I suspected.
I'm sorry to hear about your kitten. Polyps develop in the bulla and can either grow up into the ear canal or down the Eustachian tube into the oropharynx. While the prednisone may provide some temporary relief, with the head tilt you describe, your kitten will probably require surgery. If the cost is prohibitive, you might get another quote for surgery or see if your veterinarian offers any payment plans.
