Is overgrooming a recognized behavioral disorder in cats?
We have a patient that licks and bites at its flanks, sometimes coupled with periods of muscle twitching and vocalization. Our diagnostic work indicates no dermatologic or other medical cause.
The behavior that you describe characterizes what is variously called feline hyperesthesia syndrome, rolling skin disease, neuritis, twitchy cat disease, psychogenic alopecia, and atypical neurodermatitis. The syndrome can include such behaviors as biting or licking at the tail, flank, and anal or lumbar areas; skin rippling and muscle spasms or twitching (usually dorsally); vocalizing; running; jumping; hallucinations; and self-directed aggression.1
