True. I am not EVEN gonna look at the twisty cats. Sounds terrible.

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.

I don't believe that munchkins are a recognized breed, and some appear by pure chance rather than deliberate breeding.

IMO, I don't think that breeding for desired characteristics is inherently wrong - look at every domesticated animal species, including cats. The short legs are not an objectively harmful mutation; my main concern there is (as you mentioned) whether or not it comes with health problems.
