A cat with rabies is viciously, dangerously mad, but only slightly less frightening is a cat with feline epilepsy, also called rolling-skin syndrome and neurodermatitis. An affected cat may bite at her own back or tail. She may experience hallucinations that cause her to run around frantically, sometimes attacking objects or even her owner. Seizures similar to those of human epilepsy may last for several minutes. The good news for cat owners: the syndrome can be treated successfully with drugs.
