We bought this for our bunny, who was getting bored in her cage overnight. It's very well made, and she went for it right away. The first thing she ate was the straight pieces sticking out the top, and enjoyed dismantling it! We hung it on the side of the cage, which was very convenient, but within a few days, she'd chewed the rope apart and it would no longer hang. Unfortunately, when it couldn't hang anymore, she lost interest, and now it's just laying in her cage. If there was a way to prolong the life of the strings holding it up, that would be perfect!
