My cats love it. It’s made of cardboard, so of course scratches appear over time. Our clever cat fiddles with it, while our laid-back tom just watches and waits to get a turn! The price-performance ratio is spot on. And if the cats tear it apart or bite/scratch off a piece, it’s not as dangerous as plastic or threads. Clear recommendation. The only annoying thing is that you have to remove the little punch-out pieces from the small holes at first, but it’s worth it for the cats’ happiness.
