Just thought I would ask if anyone knows why a WTF would spend all day sleeping on the ground? The second the lights go out at night he comes out and climbs up into his little tree to hunt and hang out, and stays in the tree until the sunlight comes in in the morning. He hasn't always done this, and used to sleep in his tree. He has plenty of hanging plants to hide under while on his tree, so it's not an issue of him feeling secure up there.
I'm not especially worried since he acts fine and is eating/soaking/pooping normally, but this is just a little strange for him.
