I would have to say that the absolute neatest thing Severus has been doing lately is spending a lot of time around the front of the viv, against the glass. He's actually burrowed under his bedding, against the glass. It's like the snake version of an ant farm. You look over and see this snake under his aspen, but you can actually see him in the little tunnel. And some of his tunnels seem to retain some of their shape after he's moved on, I guess because snakes are so terribly careful and precise. I mean, more so than a cat.
Otherwise, nothing too funny, I don't think. He was on the edge of his water bowl once when I approached, and he backed up his top part (pulling his head and neck back) and it ended up in the water, but he didn't even notice. And it was cute when he threaded himself through his log hide, with his head out one hole and the rest going in another.
