The only kitten we have available right now is the brown straight eared boy. He has a ring tail, a rare natural trait where the tail tends to curl one way. I've seen it before on some rescue pets at cat shows but this is the first we've seen in our own cats. His tail is still flexible and he can bend it the other way but when we walks and plays or wiggles his tail it makes this cork screw motion. It gives him tons of personality as he looks happy or curious all the time.
