Another quick way to provide safety to the shelves is to get a sheet of Plastex from Home Depot (Thanks, Kathy) and cut up pieces large enough to cover the shelf and the extra space. Then drill holes in it and fasten to the shelf with zip cable ties. Trim off the extra length after you've tightened them. Plastex is a 4x8 sheet of solid 1/8" thick polyethylene made for covering walls. Just mark the size and cut with a heavy duty scissors or a utility knife and straightedge. The extra can be used for covering any floors in wire cages. I still put some kind of cloth on the floors anyway, fleece, blanket, flannel, etc. For the ramps I cut strips of non-fuzzy polyester blanket (the cheap type less that $5 at Wal-Mart) and fasten them to the ramps with six little 2" clamps. Cut them about 3" wider than the ramp to allow enough to turn under to be clamped in place. If you can't find the Plastex ask about it. It is there but in different places in each store.It will be in back by the glazing. rice $19.99 per sheet. Carol J Owens Ferret Friends, Inc. Tucson AZ [Posted in FML 6254]
