Debbie, I bought something called a Kitty Diplomat that you put under your doors to stop the digging. You could probably go to a hardware store that sells plastic carpet runners and cut it to fit under the door and would work just as well. They are clear plastic with spikes on the underside and are cut to fit around the door frame. It stickes out a couple of inches out of the front and back of the door. At first, one of my ferrets tried to dig the carpet in front of the mat. But when it didn't seem to budge, she gave up before she did any more damage. Good luck! Jeannette [Posted in FML issue 2348]
