It took a while to assemble, as instructions were not very specific, but when it finally was complete our two young cats discovered it immediately and have had many hours of enjoyment on this playground. They love surveying the room and the yard from their high perches, and the cubby holes provide plenty of room for sleeping. The scratching posts and climbing posts give them lots of chances for keeping in shape. Our cats, Thelma and Louise, would thank you themselves if they could! meow.
