Feline Hyperesthesia Syndrome

From Wikipedia, the free encyclopedia

Feline Hyperesthesia Syndrome, or FHS, also known as rolling skin disease, is a rare illness in cats.

The illness is characterized by episodes, or attacks, usually occurring daily or more often.

It is often described as a seizure disorder but the cause is, in fact, unknown.

During an episode cats show a number of typical signs, including skin rolling or twitching, self-directed pouncing or aggressive behaviour (such as biting or attacking the tail). There may also be pupil dilation, vocalisation and a general increase in activity.
