My guy has a tail that goes a little to the side. I think it's great because it makes it so that I don't have to do cleanup after he uses the restroom. Some of them have tails that block the area and it can get quite messy.
Norms tail is bent a little, he has some spine issues the vet was able to tell just by looking at his tail. We did an X-ray and he has a couple vertebrae that are closer than they should be.
