The Manx is known for its lack of tail and unique gait, affectionately called the Manx hop. The breed now includes the long-haired Manx, formerly known as the Cymric. It is recognized by its robust and round appearance; the Manx can be drawn entirely in circles. The head should be round, with round cheeks, medium in length with a well-developed muzzle and strong chin. Ears should appear round, wide at the base with rounded tips, they should be widely spaced and set slightly outward. There should be slight furnishings in the shorthair and full furnishings in the longhair. Eyes in the Manx should be large, round and full with eye and coat color matching.
The body is solidly muscular, compact and well-balanced. It is powerful without coarseness. The back should form a smooth arch from shoulders to rump and complete the round look. The Manx gene is dominant, this means kittens can have a full or short tail, a rise (rump risers) or no tail (called a rumpie). Some breeders have even recorded all tail lengths in a single litter. The Rumpie and Rump Risers, however, are the only variations permitted for show in the Manx category. There should be no bone or bump that stops the hand of the judge. The legs are heavily boned and set well apart; the hind legs are noticeably longer than the front with neat paws.
The short coat should be double and dense, with a feeling of being well-padded. It should be slightly hard and glossy in appearance. The long coat should be of medium length, dense and well-padded. It is to be soft and silky, with a healthy gloss. The Manx comes in about 30 colors and patterns.
