The Munchkin, also known as Sausage Cat is a breed of cat characterized by its very short legs, which are caused by genetic mutation. Compared to many other cat breeds, it is a relatively new breed, documented since 1940s and officially recognized in 1991. The Munchkin is considered to be the original breed of dwarf cat. The name "munchkin" derives from writer L. Frank Baum's diminutive inhabitants of Munchkin Country, originating in the 1900 novel, The Wonderful Wizard of Oz.
