I love this cat tree! My cat loves to sleep on it every day and will even stop mid-play to drink water from it and then play again. Which I adore because I know it can be hard to keep cats hydrated. It's super tall and feels very sturdy, so no worries there. I did take off the hammock and puzzle box thing. He's a little big for the hammock and it gives him more room to scratch and jump around. I'm planning on using the "puzzle" box with the balls to do something else around the house with it so he has another spot to play. I'm glad my baby has enjoyed his cat tree so much! He definitely enjoys scratching and playing and being up high on it. It was easy to put together, came with all the materials to put it together, and the instructions were easy to understand. Overall, awesome cat tree!
