That was weird. I had a cat with extra toes, but that is fairly common. Well not common, but not crazy unusual. My friends also have a cat that is sort of a medical miracle. It has a hole in the roof of its mouth which leads directly to it's nasal cavity. The vet said that it's amazing its still alive because most cats that are born that way die because they down on the mothers milk. They have to shave her because if they don't her hair gets caught in her mouth and she starts sneezing. And she cant's drink from a bowl because she could possible dorwn, so they use a big rat water bottle. But other than that she's lives a perfectly normal life.
