This tree is not for large cats. It was pretty easy to put together, it only took about 15-20 minutes. It was smaller than what I expected but I should have read the size of the steps and the bed closer.  My small 7 pound cat likes it and sits in the bed to get away from her brother.. But it is way too small for my large 16 pound cat. They both play with the activity box but not often. It doesn't seem real sturdy but time will tell.

Pros: Easy to put together, fine for smaller cats
Cons: Not real sturdy, not for large cats
