My kitty absolutely loves this cat tree. He will sleep on any one of the platforms. He loves every level; I never know where he'll be sleeping next! The scratching posts are also a great feature, and he scratches them religiously. Instructions for assembly are foolproof. The cat and I leisurely put it together in about 45 minutes. The toy that hangs off the second platform has been torn off repeatedly. I eventually just cut the string off and let him play with the toy (which he LOVES). Great buy. I AM SO SO SO HAPPY THAT I FOUND THIS AND WOULD RECOMMEND IT FOR ANY KITTY!
