A couple of times recently, Willow was lying on his side in his cage, and he tries to get up, but can't. And he just lies there kicking until I help him up on his belly. I'm scared to think about this happening if I'm not here, that he'll get worn out or hurt himself. The vet recommended the bottom of his cage full of hay, but I don't think that allows him to get enough grip, so I think I will look into a different kind of bedding.

Any advise would be greatly appreciated, thanks!
