Thanks for all of the wondering suggestions about making a blockade to keep my ferrets out of my box springs. My step-dad used about three layers of indusrial-strength plastic sheeting. Then, he duck taped and stapled it to the bottom of the box springs. After that, he layed about 20 wooden slats of wood across the bed frame. That should keep them from even being able to push the wooden pieces out of the way. If, by some odd chance, that they wriggle past the wooden slats, I don't think that they could claw through this plastic sheeting. This stuff is strong, plus we clip the babies' toenails weekly. Thanks again for all of the help. Shannon (owned by three carpet sharks... Sebastian, Felicia, & Snooz). [Posted in FML issue 3071]
