I have so many people comment that my cat with no tail is a Manx. I know nothing about them except that they have no tails. I tell people probably not, but it got me wondering. Can cats just be born without a tail as a fluke, like possibly from inbreeding or something? Or are there ONLY certain breeds that are born without tails? Willoughby has abslutely no tail. If you feel the right spot, you can feel a smal bone moving there but there is nothing. He is also HUGE with the biggest paws I have ever seen. They are bigger then my Himalayans. I have never had such a big cat.
