Jacci After finally giving up my beloved waterbed (Boy, do I miss that warm bed in the winter!) I switched to a traditional bed. A couple of my ferrets decided it was time to burrow into the boxspring. Having just shelled out 600 bucks for the mattress and boxspring, I wasn't willing to donate it as the newest ferret toy. So I locked up all the ferrets, flipped the boxspring upside down, and staple gunned a sheet to the frame - spacing the staples only about a quarter inch apart. Put the bed back together. Let the worst offenders out to try and get in. Hurray! Success - they were totally frustrated by the stronger covering on the boxspring. Now they don't even try. Good luck!
