Review of idiopathic feline vestibular syndrome in 75 cats.

Idiopathic feline vestibular syndrome, a peripheral vestibular deficit of unknown cause, was diagnosed in 75 cats at the New York State College of Veterinary Medicine Teaching Hospital from July 1975 to October 1984. Review of the medical records of these cats indicated that the syndrome was seen in more cats in July and August (P less than 0.001) than in other months. Clinical signs included head tilt, ataxia, rolling, rotatory or horizontal nystagmus, and occasional vomiting.
