>or am I giving them rug burn? What kind of carpeting is everyone using >on their ramps and is this happening to you? Thanks in advance! I don't use carpet, I use canvas. The kind of thing in plastic, use for crafting, you pass trought some wool or cotton thread, you see what I mean? I don't use thread on them, I just use my hot glue gun, put some on the ramp and glue the canvas in place. With that my ferrets doesn't have anymore problem going up or down the ramp. The square are just the good size (like 1/8" x 1/8"), and they never had problem with claw being stuck. Aristiana [Posted in FML issue 3336]
