We installed a cat highway in our new house and I love it! The cats aren't too sure yet, but they are old and still adjusting to the new house. The carpet pieces do outgas so I recommend opening the packaging and leaving in a separate room for a month or so. It doesn't smell bad to me (certainly doesn't smell like urethane or other toxic stuff) but it was bothersome to the cats for a while. We opted to use 80lb wall anchors rather than the anchors that came with the kit so that all three cats could sleep in the bed at the same time without stressing the screws. It installs easily and is well designed.
