The Manx comes from the Isle of Man, where a natural mutation produced cats with no tail or a short one, and the breed has been recognized for well over a century. Tail length varies widely, from none at all to a full tail, even within one litter. Manx are round and sturdy, with a short back, long hind legs and a dense double coat that sheds moderately.
Many Manx are gentle, devoted and playful in bursts, and they're known for following their people from room to room and fetching toys. They tend to trill softly rather than yowl. The gene that shortens the tail can also cause Manx syndrome, which affects the spine, bladder and bowel, usually by four months old, so a veterinary exam matters whichever cat you meet.
