In response to the owner of the ferrets who have moved on from the couch to the underside of the bed - I've done the same thing on the bottom of my bed, chairs and sofa - taken an inexpensive flat sheet and a million upholstery tacks - fold the sheet to fit the piece - tack the sheet onto the frame of the furniture - tacks very close together. On the sofa, I did need to make small holes to screw the bun feet back on. 36 ferrets since I started using the sheets - they don't even try anymore. [Posted in FML issue 3533]
