Our cat is so happy with his new cat tree!  At only nine months, this is his second cat tree. The first was fine until he grew, and then the stability of the tree and the width of the top platform were in question. Now he can jump from across the room and the Erving cat tree stays stable. And the top platform provides more than enough room fir curling up for an afternoon nap. All in all, this Erving cat tree was the right choice. My cat sends his thanks
