The Munchkin or Sausage Cat is a new breed of cat characterized by its very short legs, which are caused by a genetic mutation. Much controversy erupted over the breed when it was recognized by The International Cat Association in 1995 with critics voicing concern over potential health and mobility issues.
Short-legged cats have been documented a number of times around the world since the 1940s. A British veterinary report in 1944 noted four generations of healthy short-legged cats which were similar to normal cats except for the length of the legs. This line disappeared during the Second World War but other short-legged cats were spotted in Russia during 1956 and the United States in the 1970s. Source: https://en.wikipedia.org/
