Manx basic information

It has sturdy bone structure with forelegs shorter than the hind legs, rump as "round as an orange" being higher than the shoulders. The Manx has a soft, double coat with a short "open" look.
Head and Ears: The head should be slightly longer than it is broad, with prominent cheeks (also stud jowls in the male) which make it appear rather round. There should be a break at the whiskers. The nose is slightly longer and broader than in the American Shorthair, but with no suggestion of snipishness. Ears medium in size, rather wide at the base and tapering gradually to a rounded tip, with sparse furnishings inside. The Manx may have ear tufts at the tip which make the ear appear pointed; this is permissible. Ears are widely spaced and are set slightly outward so that when viewed from behind they resemble the rocker of a cradle.
