I have found, with every rodent I have had the pleasure to know, that they will put their stuff where they want it! No amount of arranging their spaces to please my own tastes has ever held any truck with them. I've learned to just accept where they put things. Which is to say, go ahead and put the bedding inside their house. If they don't want it there they will either move it or find somewhere else to sleep! Let them tell you what they like and don't feel bad if they disagree with you
