The Munchkin is a 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 (TICA) in 1997 with critics voicing concerns over potential health and mobility issues.

[5] Breeding of Munchkin cats is prohibited by law in several countries due to these genetic health concerns.

The name derives from writer L. Frank Baum's diminutive inhabitants of Munchkin Country, originating in the 1900 novel, The Wonderful Wizard of Oz.

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.

[1] In 1983, Sandra Hochenedel, a music teacher in Rayville, Louisiana, found two pregnant cats who had been chased under a truck by a dog.

Critics predicted that the breed would develop back, hip and leg problems similar to those that plague some dachshunds.

[9] Solveig Pflueger, a show judge, geneticist, and chairperson of TICA's Genetics Committee was a strong advocate for the official recognition of the breed.

Veteran show judge Katherine Crawford resigned in protest, calling the breed an affront to breeders with ethics.

[16] Katie Lisnik, director of cat protection and policy at the Humane Society of the United States, has said: "Breeding animals for exaggerated physical characteristics, particularly when it compromises overall health, is irresponsible".

[4] The Munchkin has similar characteristics to normal domestic cats, due to their frequent use as outcrosses.

[27] Munchkin cats are known to be at a higher risk (than other feline breeds) for severe osteoarthritis because the shorter limbs affect their activity levels and behavior.
