"charlie and spike were two kittens with myotonia congenita, otherwise known as 'fainting goat' syndrome. at the slightest sound or movement, the kittens responded by collapsing and falling into a rigid paralysis which lasted about a minute before they returned to normal.If a pin dropped they dropped too. This condition had hardly ever before been diagnosed in a cat, is rarely found in dogs and is more common in goats. The kittens were able to walk, but they could not run or jump. sadly they both died from this condition in October 2010"
