we bought him a humid hide and it has moss in it to keep the moisture longer. and yes it is only on his back. the sides of him have completely shed. he only has it on the top. and just a little around his head.... to be clear on the pillow case thing... you put a warm cloth in a pillow case and put him in it.... and thats it..... how to you keep the pillow case warm... can i put it in his hot spot in the cage...
