Sometimes when you spend a lot of money on something for your cats, they end up preferring to play in the empty cardboard box it came in.  But my cats starting playing on this while I was assembling it and remain intrigued.  It allows for all 3 (fairly big) cats to have a window seat. They also enjoy the scratching posts and hanging out in the condo. It's surprisingly well-made and sturdy - the towers need  occasional tightening (with the tool that comes with it) but that's no big deal. And it's a really pretty piece of furniture that takes full advantage of the big window in the room.
