Both my dragons do it. I always assume it means they want out. But just as I go to lift them out I think, the last time you did that and I let you out you went to the bathroom all over the floor/couch/ME/desk etc... Sneaky little bugger. Usually if they do that, I'll leave them in the tank until they go to the bathroom (assuming they are doing it around bathroom time), THEN they can come out. They've tricked me one to many times. Hey, I wouldn't want to go to the bathroom in my bedroom either. I've always thought about putting an 'inverted V' type ramp so they could go in and out as they please (supervised of course) but I'm sure they would come out, go to the bathroom in a pile of clothes then go back in and act like nothing happened. (No, really, I've just been sitting here... basking...yeah basking, that's the ticket).
