Cats
modern PixieBobs, although this may be due to the genes being diluted by several
generations of backcrossing to domestic cats.
There is an unconfirmed version known as the Munch-Bob which is a Munchkin/PixieBob
cross to produce a short-legged bobtail. In theory, any of the bobtailed or tailless breeds could
be used to produce bobtailed/tailless Munchkins.
Not to be confused with the PixieBob is the Poly-Bob (1998) which is linked to the infamous
Twisty Cats (cats bred for detrimental deformities). Poly-Bobs are not a recognised breed.
They are bobtailed polydactyls which carry the harmful form of polydactyly which also
causes gross deformities of the foreleg and front paws, including vestigial, absent or
deformed leg bones and flipper-like forelimbs. No attempt has yet been made to eliminate
these harmful effects and they represent the darker side of cat breeding (See Polydactyl Cats).
