What does a Manx cat lack?
1) a long tail “The Manx (kayt Manninagh or stubbin in Manx Gaelic) is a breed of cats with a naturally occurring mutation of the spine. This mutation shortens the tail, resulting in a range of tail lengths from normal to tailless. Many Manx have a small ‘stub’ of a tail, but Manx cats are best known as being entirely tailless and it is the distinguishing characteristic of the breed and a cat body type genetic mutation.” “There are various legends that seek to explain why the Manx has no tail. In one of them, Noah closed the door of the ark when it began to rain and accidentally cut off the Manx’s tail, who’d been playing and almost got left behind. Another legend claims that the Manx is the offspring of a cat and a rabbit which is why it has no tail and rather long hind legs. In addition, they move with more of a hop than a stride, like a rabbit. This legend was further reinforced by the Cabbit myth.” Source and further information: http://en.wikipedia.org/wiki/Manx_cat 2) long ears.
