We own 6 cats . We've been searching for a cat house that wld be suitable for not only our cats but us as well. We looked but could only find small ones lined with carpet... wanting $!20-$169 and up.  We wanted something that would keep our cats off of the furniture & to stop scratching it as well. This has solved "both" of the problems. It was shipped very quickly and only took me 15 min to put together....very easy and very sturdy!!! Our cats absolutely "LOVE" it and are on it sleeping all of the time as well as using the many sisal twine posts. We have read reviews on this sight saying that the 3 upper beds were too small. NO WAY!! We have 3 very large cats and they have no problem sleeping in them. We have this cat tree and we rate it 10 out of 10 definitely.  Thank you for a wonderful product!!
