FYI, if you don't check your snake's tail tip after EVERY SHED to make sure all the old skin came off, it can get stuck, & only a few layers of old shed on their tail tip is enough to cut off the blood supply and cause death of tissue. (hence the black dead tail tip- which can also cause a systemic & fatal infection in a snake!) That was a husbandry issue, it was something that YOU could & should have prevented.
