There's a ledge about 1/2" wide and about 1/2" below the screen on my snakes enclosure. He's about three months old, maybe a bit more, around 18" long. He can fit about the first third or so of his body, including his head, onto that ledge. Then he pulls the rest of himself up as best he can, but he won't fit. He's been up there as long as a minute maybe, before he falls 12" down to the bottom again. And again and again. Seems to be his favorite thing to do since I got him three days ago.

At first I thought it was just a bit goofy, he'd learn to stop eventually. But now he's scaring me a bit. He's getting better at getting up, better and lifting the rest up after. I don't think he'll get stuck, I don't think he'll get too close to the lamps, but it seems like he's bound to hurt himself somehow. His falls are getting harder as he gets more of himself higher off the ground.

I think I'll have to glue something up there to fill it up. Any best ideas? Am I worrying too much?
