Oh boy.... what can I say... SUPER unsteady. Just buy armarcat and save yourself figuring out which tree would work. None of these are worth it. Cat broke her tooth due to how unstable this is resulting in a $1200 surgery with her tooth extracted.... it literally FELL. 

Also, you won't be able to return it for free since you'll have to pay shipping. I really want to recommend items from wayfair... but not worth your time, a headache, and a $1200 bill, with your cat in pain for WEEKS.
