Is his regurging his meals common for him? Does he always eat 3 mice at a time for his weekly meal?If so and your temps and your husbandry are all correct my advice is simple,take him to a reptile vet ASAP.Regurging is not a normal thing and could be caused by several things.Now the wound on his back is possibly easy to figure out.Is there something in his enclosure that has any sharp edges? Snakes do not rub there skin raw to the flesh unless they have something that causes this to happen.Could you give a some info on this snakes history since he has been with you and his enclosure description? How long have you had him? Is he a baby or adult? What are the temps in his enclosure? Maybe once we know a little more about him we might be able to help you with him.Originally Posted by Paulzy
