One maijor problem I have had is with my ferrets digging. Now I know how ferrets have instincts to dig burrows to sleep in, but I do not think that accounts for Felix digging a large piece of wood right off of a door frame. The piece was about 7 feet long, but he ripped it right off the frame. Before that, he or Tofu managed to dig right through a carpet in their attempts to get under a door. This was stopped by nailing some clear plastic over the hole, but my sister and I frequently manage to impale our feet on the nails, which don't go down with the plastic when they are stepped on.
