I was given a grey kitten 8 years ago and was told that he had a small kink in his tail. I have since been told that this kink is a problem that persian cats are prone to. He is not a pure bred cat, but he is very large and has a long blue coat. Do any breeders of persian cats know of a condition that affects the tail in this way? It feels as if it has been broken and then healed out of line. It doesn't hurt him and he has full movement and feeling in it. I used to have a tortoiseshell cat, I was told that they are a vets nightmare because they are prone to using their claws. Does anyone out there know if this is true or not. My tortoiseshell was very scratchy and bitey.
