Our 3 cats love it, especially the scratching posts as they can stretch themselves up fully. They love the hammocks even the largest who is a bit too big but still loves it. The platforms are great for the kitten to build her confidence and muscles before she becomes an outdoor cat. Only problem may just be in the way we built it becuase it lurches forward if pushed but it is still stable enough for the cats.. Vanessa. Birmingham, GB. Sun Feb 09 2020
