The Manx cat is a breed of cat noted for its genetic mutation that causes it to have a shortened tail. The length of this tail can range from a few inches, known as a "stumpy", to being completely nonexistent, or "rumpy". Manx cats display a range of colours and usually have somewhat longer hind legs compared to most cats. The cats have been used as a symbol of the Isle of Man on coins and stamps and at one time the Manx government operated a breeding centre to ensure the continuation of the breed.
