"charlie and spike are two kittens with myotonia congenita, otherwise known as 'fainting goat' syndrome. at the slightest sound, the kittens respond by collapsing and falling into a rigid paralysis which lasts about a minute before they return to normal. This condition has hardly ever before been diagnosed in a cat, is rarely found in dogs and is more common in goats. The kittens are able to walk, but they cannot run or jump. aside from this they are normal."
