This cat tree is a great price for the features it offers compared to other products in its class. Overall the product is well made, but the top level is pretty tippy. I think the base needs to be a little wider to support the height. I have an 11 pound cat that is fairly long and tall. He fits in the house part easily and enjoys playing within it. When he gets on the top level and rolls around trying to get at the dangling ball, it could easily tip over if you don't have it secured some how. Overall he loves playing on it and uses the scratching with no problems at all.

Pros: Easy to assemble, good quality construction, good features for the price
Cons: top level is too tippy
