Actually some people do breed cats for deformities - Google "munchkin cats" or "twisty cats". Example:

Munchkins I'm undecided on, but breeding twisty cats seems reprehensible.
As far as the munchkins go, I cannot believe they allowed that to become a breed. You are just asking for health problems when you start to deform an animal through breeding.
And munchkins look wrong, too. It is not cute, IMO.
Ah yes...Vicki Speirs....Frankenstein woman. Another good reason for beheadings.
