Normal or broken?

I have had my 7 month old kitten for 4 months. My mother was petting him yesterday and noticed something that I never had before. She said that it looks like his tail has been broken. Sure enough, when I felt it, I noticed that the very tip of it is bent and crooked. It feels like the bone (?) in the tail is bent at a weird angle. It has never seemed to bother him, and I have no idea if the tail was that way since birth, if it happened at the foster home, or at my home. I know that I have stepped on his tail a couple of times before (he is always underfoot). I hope that I did not break his tail. Since it is just at the very tip and doesn't bother him, I am not sure if it warrants a vet visit or not.

This could be a genetic thing. I have heard that Siamese cats can have a kink in their tails. He was described to me as a "Siamese mix" when I adopted him. He does have the pointed markings and blue eyes, but I have no way of knowing for sure how much, if any Siamese he has in him. None of his siblings look like him. Could a cat that is not 100% Siamese (or not at all) be born with a kinked tail, or do you think he could have injured himself? I would feel really bad if I broke his tail somewhere along the way by stepping on it or something.

Yes, he could very well just have a kink in his tail. We currently have a 4 mo old calico in the rescue with a kink in her tail, the only one with such tail in her litter of 6. However, one of her brothers' tails was broken before we got them at 6 wks old. About the last 1/3 of his tail flops over; however, it kept its blood supply and the nerves function properly...he has even learned that he can move that portion of his tail and can straighten it out completely at times. =)

One of my cats has that, too. Just the tip is turned at about a 45 degree angle from the rest of her tail. You can't really notice it looking at her, but you can definitely feel it if you run your hand down her whole tail. I think it is just a kink.
I would imagine if you had accidentally broken your cat's tail, you would have noticed him acting differently at the time. It probably would hurt pretty bad!
As long as it doesn't bother him, or cause him pain, it's fine and normal
