I've gone threw many pictures here on this forum and I see some people have hide aways some don't some have all three some dont some have just a cuddle cup and no pigloos. So whats up with that? I was always told to have a pigloo, now I see some people don't use them at all and have cuddle cups and cozies. So I guess my question is do you need all three or a few cuddle cups and cozies?
