So about 2 weeks ago my ball python discovered that he is capable of wiggling under his astro turf so he can hide under there. He has two cave hides on either side of his tank, but ever since he figured out he could get under the turf, he refuses to go into them. The problem is, he hasn't moved for days. I've checked on him a couple times a night, but he's never come out to explore / climb around like he usually does. He is always in the same position as when I leave him. He eats fine and is not going to be shedding anytime soon. Is this something I should be concerned with?
