Hi All! When I needed to create a couple of cage ramps for an elderly ferret a few years ago (for a Super Pet cage) I went to the local pet supply store & bought some extra large/long bird/parrot ladders. When I acquired my current baby (Kira) I went to Meijer (Kmart or Target proably carry similar items) & bought a couple soccer/hockey socks & covered each ladder to create ramp without worrying about ferty feet falling thru as they are racing through the cage (the elderly ferty girl did not run anywhere, but Kira is like lightning) Hope this suggestion helps!
