The Manx cat, in earlier times often spelled Manks, is a breed of domestic cat (Felis catus anura) originating on the Isle of Man in the British Isles, with a naturally occurring mutation that shortens the tail. Many Manx have a small stub of a tail, but Manx cats are best known as being entirely tailless; this is the most distinguishing characteristic of the breed, along with elongated rear legs and a rounded head. Manx cats come in all coat colors and patterns, though all-white specimens are rare, and the coat range of the original stock was more limited. Long-haired variants are sometimes considered a separate breed, the Cymric. Manx are prized as skilled hunters, and thus have often been sought by farmers with rodent problems, and been a preferred ship's cat breed. They are said to be social, tame and active. An old local term for the cats on their home island is stubbing. Manx have been exhibited in cat shows since the 1800s, with the first known breed standard published in 1903.
