I spray down his cage a few times a day, and I even soaked him for a few minutes yesterday (I didn't dunk his head because I didn't want to hurt him). His skin looks ready to come off, and it has for a few days now. He has shed most of the skin from his belly now and also from his eyes and face. However, his "back" (so to speak) still has the old skin stuck to it. There are tiny pieces of shed skin all over the tank now. I don't understand what I could be doing wrong? What should I do? I thought snakes were supposed to shed all in one piece?
