"Feline Hyperesthesia Syndrome, also known as rolling skin disease, is a rare illness in domestic cats that causes episodes of agitation, self-mutilation, and a characteristic rippling of the skin when touched. It is often described as a seizure disorder but the cause is unknown. During an episode cats show a number of typical signs, including skin rolling or twitching, self-directed pouncing, or aggressive behavior such as biting or attacking the tail. There may also be pupil dilation, vocalisation and a general increase in activity."@en . . . "Feline Hyperesthesia Syndrome"@en .
