He may also not like the feeling of it against his skin when he burrows down far enough to touch it. And I would worry about when he burrows down that he could tear it or put a hole or something in it. I know that's a real big what if but I wouldn't want to take the chance. And if he does put a hole in it or something when he goes back to burrow in that hole in the morning he could end up under that wrap. Again they are what ifs but there is a possibility I could happen.
