Mine sits in his warm hide with his head hanging out and licks a lot. I heard him make a noise twice or at least I believe it was him I didn't actually see him but theirs not much else it could have been, it sounded kind of like a cat throwing up a hairball. He eats fine and when I take him out he's as active as usual. I've been thinking he needed to shed for about a month and have sprayed him periodically but he still hasn't shed, and he begs for more food now too. Should I be concerned thanxs
