My cat was interested the moment I took the Tower of Tracks out of the box. It snapped together in seconds and he was on it just as fast. It keeps him entertained and active. He plays with the tower several times through out each day. He gets pretty wild with it and jumps on top of it, slides it across the floor and he really likes to flip it over and play with it upside down, but it is holding up nicely to all he does to it. I like knowing he is entertained when I have to be gone. It's so simple, but it's a great toy for cats and well worth it. I recommend this for anyone with cats.
