What do you ruminate more or less the Munchkin and Sphynx Breeds?
Answers: I don't think there is anything wrong with breeding Sphynx cats. The single thing you are altering is the hair. I do think breeding Munchkin cats is cruel, because like genes that shorten the legs also weaken the heart muscle, and they usually die young. Besides, in that are too many ordinary cats being kill every year for people to keep on breeding more.
Sphynx are ok - I prefer fur on the cat, but they do have a Rex nature and I like them for that only.
Munchkins?? I don't think they should be continued to be bred - its a short time ago wrong. Cats were made for running, leaping and jumping. Munchkins can run, but they really cannot leap and leap like a normal cat. Sometimes a mutation is not one you want to continue.
