Wow, thanks everyone for your input. I'm less worried now. I noticed my humidity dipped quite a bit lately when it was at a good steady spot. I'll probably try the misting/sponge technique. I never thought about the sponge.

I'll probably try feeding him again.

I'm trying to avoid handling him to get that extra shed off until he has 1 or 2 more good feeds. He's only had 1 since I got him.

I thought about pre-scenting, but I'm afraid the mouse will stress him out because usually they go crazy in the little cardboard box they come in and I don't want the mouse stressing the snake out. I might give it a try and see if it works. The mouse usually craps and pisses all inside the cardboard box
