we needed something low with a scratching surface and a place to sleep/hide/play with a smaller footprint for 2 1.5-year-old rescue/foster cats. in almost all of those respects, this fits the bill. the cats we purchased it for haven't quite figured out that it's OK to scratch it yet, but it's only been a few days, so hoping that'll happen with time. as another reviewer mentioned, our cats tore the hanging ball off the 1st day. the toy wasn't a reason I chose this, but considering how much the cats really enjoyed playing with it for the few hours it lasted, I'm sorry it's gone, and wish it had been attached more securely. also as another reviewer mentioned, the cushioned "pad" for the bottom of the tunnel doesn't stay put. our cats pulled that completely out of the tunnel almost immediately. I don't know if they did it simply because they discovered that they could (you know how cats are), as part of normal play/exploration, or because they preferred the tunnel without it. I removed it for now, might try putting it back in a few days, see what happens. 1 cat is enjoying this more than the other, I often find her inside it, or just perched on top of it. her brother, not as much. at least not that I've witnessed. again, it's only been a few days, so I hope that they both grow to like it equally and begin to scratch it. since they're small and like to cuddle together, I'm also hoping to find them sleeping together in it. it's definitely roomy enough for 2 cats to hang out inside. one of the "feet" attached to the bottom of the tunnel is slanted. it didn't happen during transit, it wasn't loose or anything, so it appears to have left the factory that way. even tho it's wonky to look at, it's attached very securely, so I'm thinking it shouldn't affect the overall sturdiness. but considering this wasn't inexpensive, a little more quality control would've been appreciated. maybe $15-$20 over-priced, but overall I'd give this a solid 4/5 stars. this is a (mostly) well-constructed, thoughtfully designed, compact piece that has a lot going for it. I can see it being great for older cats who are past their climbing/jumping years but who still want something accessible for sleeping, playing and scratching. I'd recommend it.
