My Ball Python, Gregory, hasn't come out of his tight hide box (a dragon head with moss inside) for a few weeks now. I have to remove the entire dragon and put it in his feed box to feed him weekly. He does eat but just sticks his head out enough to eat the mouse and goes back inside. I can't force him out because it's a very tight fit. Has anyone had this issue before? I've had him for 6+ months and he has never done this before.

Any advice would be appreciated!
