I get so many compliments on this tree - it sits in the corner of my living room but doesn't surrender the room to my cats.  Many different features - great for a multiple cat home and as in my case for extreme age ranges.  There's something for every mood - you know what I mean.  EASY assembly.  

Pros: great price, easy assembly, multiple features, unique design
Cons: I've had it for a month and haven't come across any.
