My family has a 2 month old shorthair munchkin kitten. They want her to have 1 litter of kittens, after which they were planning to have her spayed.
Since bringing her home, I have become aware that following Western standards, this is considered a problematic breed. Following my own research, my opinion has been that because she is already a member of our family, we should raise her to have as good a life as we can provide, but if munchkin cats suffer from health related issues as a result of their dwarfism, it would be unethical to allow her to breed further and bring more munchkin cats into the world who would certainly suffer from the same issues.
I live in an Eastern country. I am aware that the standards followed by vets here are different (more lax in some areas and more strict in others); we have asked a few vets in the area for their opinion, and they have told us that it is considered fine; that besides for visually having shorter legs, munchkin cats are otherwise just like any other cat, and that the dwarfism isn't a problematic trait in itself that would cause health problems.
Anyways, I was hoping for someone to explain to me what specific health related problems and challenges, if any, that munchkin cats will face as a result of their dwarfism that would make it unethical to allow our kitten to have a litter. It would be helpful if you could provide any references from recognized veterinary science sources.
