My cat Scarlett loves these!! I definitely recommend these to anyone who lives in a smaller space and wants their cat to have some more stimulation/movement. If I ever can't find her somewhere walking around in my apartment I know for sure I'll find her laying on the top shelf. She loves having to climb up to them and climb between them, which I think has helped her get a little exercise throughout the day. She even likes to have her toys thrown at her while she's up there so she can try to catch them.
