We used to have a problem with our fuzzies getting under our couches. Both couches are the kind that fold out into beds, and are a playground for ferrets. They would get under them and then in them and only time could get them out. Luckily, both couches have a "border" around the bottom. That is, the fabric hangs down to the floor. I went to one of those large hoe supply stores and bought enough of the black corrugated plastic that is meant for yard drainage. It comes in either 8 or 10 foot lengths. I believe the 4 inch size was a perfect fit. Just cut the plastic tile to fit VERY snuggly between the legs. Lift the couch slightly to position the tile and the couch will then hold it in place. I did both ends, front, and back. The "fringe" hides the tile. No one will ever know it is there. An added benefit is that the ferrets LOVE IT. By placing the tile at the front and back far enough out that they can crawl into it, they now have four new tunnels to explore. Show them how to do it a couple of times, and they will crawl through on their own during play time. You know where they are because you can hear their little toe nails clicking through the tile. You still have to watch that they don't crawl on the couch and then disappear between the cushions, but that is a lot easier to control than keeping them from going underneath. Another tip....we use rabbit pellets for litter. None of our fuzzies has ever even tried to taste them. The pellets are cheap, have a pleasant smell, absorb nicely, and are biodegradable. I just pitch the whole litter box contents onto the lawn. Have used them for years and never had a problem in the litter box or on the grass.
