Great product! Our kitten loves it! He plays or naps in the House portion all the time, loves the hanging toy that came with it, and loves to run up and down it for hours!  We keep his toys in the hammock part and he loves jumping in a out of it and brings the toys in and out of it. He doesn't really relax in the hammock just plays with it and we've trained him to put the toys away in there too! All in all its a great product and I would highly recommend for someone who has a kitten, an older cat may not utilize all the fun features it has.
