We just scored a sturdy-looking cat tree at the "too good to waste" section of our dump. Dh was less pleased that we were unloading a bunch of junk, only to come home with another project, but I know our six rescued cats (and I swear, we're actually dog people!) will be thrillled. We'd like to replace the carpet and sisal rope on it, and basically just use the frame, which includes flat areas and a round tube. How would we attach the carpet and hide the edges? What would we use? I'm sure they have some strong (and toxic) carpet glue out there, but we'd like something less poisonous for our house!
