product seems sturdy and well built for what it's designed for, I just wish my kittens would utilize it, so far they haven't totally adjusted to I guess. Instructions are vague because it's only pictures and you have to determine exact way parts go together, only thing listed is parts and how many of each and which number screw is used in a particular place 

Pros: nice looking, sturdy, solid
Cons: lack of written assembly instructions only pictures
