To Lauren Sautner: I, too, have experienced the problem you are describing with one of my ferrets (C-pi, RIP) getting up inside the box springs and digging away at the batting, stashing toys up inside there, and sleeping. It was very cute to see, but very destructive! My solution was to take a fitted sheet and fit it over the box spring from underneath. I then bought some of those tacks you can buy at fabric stores for holding down upholstery and attached the sheets in place so she couldn't pull the edges down and get in from the side. Voila, problem solved! Of course, she missed her little hiding place ... Linda [Posted in FML issue 1332]
