Front legs pointing back, looks totally chilled, typical position of legs when they feel OK. Looks funny though, they do weird things at times.
He often lays with legs folded back but I have never seen crushed him in the corner like that. He had one back leg up under him. Looks painful. He stayed that way for awhile and napped. Look at the guns and chest on that guy!
I think we all have slept in weird positions and woke up stiiff, wonder of they do the same. He certainly looks fit and healthy. You sure he's not been doing "power lifting" with the rocks in that tank
Sometimes when he sits with his front end up off the ground you can see how muscular the front of the body is. Pretty neat. I always think he looks too skinny to me. You know how slow they grow. I've had him a few years now and I know he has grown by looking at old pics but it sure is slow.
