This summer I purchased two playpens for outdoor entertainment for my ferrets. These playpens had no tops, so I kept a constant eye on my furkids while they were enjoying this new experience. Shelley, you mentioned wondering whether or not the ferrets would dig out underneath the playpens. The answer is yes, they can. I had two instances where my little rascals managed to escape through tunnels they had dug under the bottom playpen wires. In the first instance I had turned my back long enough to put an inch of water into a plastic pan with the garden hose to help keep the ferts cool. When I turned back around, Eve was gone and I spotted her 60 feet away at the back of my property playing in a lawn rubbish pile. Later, some e-net friends suggested I place a tarp under the playpens to avoid their digging their way out. This worked very well. These little rascals of ours are like two-year olds! You just can't let them out of your sight when they might be in danger. Cordially, Greta Hoisington [Posted in FML issue 4266]
