Pippo's fav hideout is the closet too. When we open it he jumps in and plays with any strings hanging from our clothes (e.g. drawstring pants) and stays in there for hours.. he can stay in there the whole day unless he gets hungry and meows for us to get out. The thing is, he's so quick that sometimes we can't see him go in and we end up spending hours looking for him only to find him in the closet!
