Manx

The Manx is a breed of cat with a naturally occurring mutation of the spine. The hind legs are longer than the front legs, giving the cat a semi-hunched appearance. Some manxes have a small 'stub' of a tail, but most are entirely tailless. The mutation is not always harmless - the mutation shortens the spine, usually chopping off the tail, but it may also cause serious damage to the torso and the nerves including an 'open' spine, bowel and bladder problems, and spina bifida. This is called 'Manx Syndrome' and is most likely when two completely tailless Manxes are bred together. For this reason, breeders generally breed a 'stumpy' or fully-tailed Manx with a 'rumpy' cat to minimise the chances of serious defects. Fifty percent of a tail/no-tail mating will be fully or partially tailed, and fifty percent will be tailless. Cats without Manx Syndrome generally live to a ripe old age, and are no more or less healthy than tailed-varieties.

Manx kittens are classified according to tail-length. The ideal show manx has no tail whatsoever, and it is known as a 'rumpy'. Some kittens have a small stub of cartilage under their fur that may be felt when the kitten is happy - these are called 'risers'. A kitten with one or two tail vertebrae is called a 'stumpy' manx, and finally some kittens are 'longys', with a complete or nearly complete tail. These last kittens may not be shown as Manx, but because they still have Manx genes their kittens may or may not be tailed. Kittens with tail-stubs generally have them docked at about a week old for medical reasons - the partial tails are very prone to a form of arthritis that causes the cat severe pain from the age of four or five years. Removal of the adult tail would be a much more traumatic procedure for the feline than it is for the kitten.

Manx cats may have a long, short or medium-length coat. Long-haired manxes are registered with some show registries as Cymrics, and shown separately. Other registries consider the Cymric a variety of Manx, and are shown as 'long-haired Manx' and 'short-haired Manx' respectively. All Manxes have a very thick fluffy double-layered coat, regardless of its length.

The Manx breed originated on the Isle of Man, hence their name. They are an old breed, and tailess cats were common on the island up to two or three hundred years ago. It is unknown exactly how the mutation originated, but legend has it that it was the result of cats surviving a shipwreck centuries ago.
