A 13-year-old, male, castrated American domestic shorthair cat is brought to the clinic by his owner for evaluation. The cat had several episodes of disorientation and seizures that spontaneously resolved 3 and 6 months ago. The current episode of disorientation was noted when the patient was found in a closet with his head pressed against a wall. When removed from the closet, his gait was unsteady, and he appeared disoriented and poorly responsive to the owner. One week ago, the patient was diagnosed with a right ear infection and has been on topical antibiotics. The signs of ear infection have improved with treatment. At the visit 1 week ago, laboratory studies (CBC, blood chemistry, urinalysis) were obtained, and the results were unremarkable.
