This was by far the best deal I found out there and my kitten loves it ! When she jumps to the top level it does wobble some, but I don't worry about it falling over. She loves playing with the mouse and always try's to take it down the tree with her, after a few attempts she was successful and it came off (which I expected), but I just tied it back up there and she's back at it ! Definitely a great purchase for cats that love to climb
