Feline Hyperesthesia syndrome(feline psychogenic alopecia ) aggression manifests itself spontaneously. Cats with such syndrome are extremely sensitive when touched along the spine. To avoid this bad habit, it is very important that the cat is not stressed.
“Hyperesthesia” means “abnormally increased sensitivity of the skin.” It may begin with signs typical of feline psychogenic alopecia , and then escalate. It is known by many names including “rolling skin syndrome,” “twitchy cat disease,” “neuritis,” and “atypical neurodermatitis.”
Hyperesthesia syndrome occurs more frequently in oriental cats, breeds like Siamese, Himalayan, Burmese, and Abyssinian. This syndrome is most common between 1 to 4 y.o. cats. Hyperesthesia syndrome seems to have no known cause and aggression is called idiopathic.
