I purchased this tree about a week ago for my 15lb adult cat. Shipping was fast and free. Easy minor assembly after delivery. My cat loves it but I found it to be too tall for him. He jumped to the ground from the very top tier and landed awkwardly so it made me worried he could injure himself. Instead of returning it and purchasing a smaller one, I just removed the top tier and it’s perfect. It’s sturdy but it does wobble a bit when he jumps on it so I have it leaning against a wall to keep it stable. The scratching rope is attached securely and stays in place while he scratches. Overall great tree, would recommend as long as you’re comfortable with the height.
