The name gives you the general idea, but not the whole story, of this cat: short, but not a real dwarf, for the only thing dwarf about the Munchkin is the leg bones. Essentially this cat is normal sized but with short legs, the result of a genetic mutation.
There is a lot of controversy about whether it is healthy (or ethical) to deliberately breed such cats, and for that reason the cat fancier associations have been slow to recognize this breed. Yet the Munchkins have their fans, not only because of their distinctive look but also because they are so playful and inquisitive. There are both longhaired and shorthaired Munchkins.
