Hello everyone... I am a new member and need help desperatly. The other day my niece noticed the tip of my cat's tail was hanging by what looks to be a nerve of some kind. It is still attached to the actual tail but is dangling by this string. I am not sure what a cat's tail is made out of exactly but it doesnt seem to bother him. He's still eating and drinking water. His routines are the same. The problem is he lives on the roof because our dog doesnt get a long with him. I am thinking maybe our dog bit him and caused the injury but im not sure. He is a stray but he comes to eat at our house so we claim he's our cat and I care about him a lot he was born behind our water heater but he's not people friendly. He will not allow us to get near him especially now that the dog is outside. I dont know what to do! Help!
