Manx

The Manx's personality is probably the reason the breed has won such a strong following despite the physical difficulties and breeding challenges. Manx cats make great household companions. They are intelligent, active, and fun-loving cats that manage to express themselves very well without tails to swish around. Manx get along well with other pets (particularly dogs), and form strong bonds with their chosen humans. They enjoy a good game of fetch and are fascinated by water, but only on their terms, of course. Manx are exceptional jumpers because of their powerful back legs. No cupboard or shelf is safe with a Manx around.

The Manx is known for its unusual rabbit-like gait, known as the 'Manx hop.' While some breeders and fanciers consider the walk to be a result of skeletal abnormalities related to the Manx gene, others consider it merely a result of the short back and the long hind legs as noted in the Manx standard.
