Munchkin Cat

Advocates and critics
The Munchkin cat is the result of a genetic mutation and some people believe that they should not be continued to be bred but others see little difference in a short legged cat breed and the short legged dog breeds such as the Dachshund, Bassett hound and Corgi.
There is controversy among breeders of pedigree cats as to what genetic mutations are abnormal and potentially disadvantageous to the cat. The Australian Capital Territory (a territory of Australia) government consider the munchkin breed to be "malformed animals" and the deliberate breeding of them "unacceptable" because of the "genetic health problems associated with such breeding". Owners and Breeders of munchkins declare them to be "a sound breed" that is "ideal" for small homes and not particularly susceptible to health problems.
Small litter sizes when two munchkin cats are crossed indicate that embryos that are homozygous for the munchkin gene are non-viable.
