I have a baby panther that is around 4 months now that has a ring of shed that has turned the very tip of his tail black. I have tried to remove the shed but have not been able to without really digging at it. I am not sure if it is too late at this point but wanted to see what anyone else would do in this case. He is the only baby out of 21 in this clutch that had this problem. The pic is not the clearest but its the only one I have at the moment. I wil try and get a better one tomorrow.
