The house we just moved in has windows higher up from the floor than our previous residence and so needed something where our cat could see out.  When the box came, he must have known it was for him because he sniffed and pawed at it till we pulled it out and put it together!! Now he can get on the top and see out the window and even sleeps there too! The 3rd floor his is play section and has a ball plus as you might expect sleeps there as well!! And for the money was quiet a find!!! Easy and quick assembly which was a plus. Would add a photo but I only have a small phone and wouldn't do justice to how great it looks with our fur member in it. All I can say is - it's a real treat!!!!!
