My cats love this kitty mansion absolutely the best brand I have gone through two other cat trees (will not name brand sorry) and they end up breaking or falling apart from the rough play by my two kitties but this kitty mansion Redwood cat tree still looks brand new even after 4 months of hard playing and still continuing I'm looking to buy another but different model for my living room now (other one is in my bedroom for nighttime play) I truly recommend the kitty mansions over any others. 

Pros: Great price and VERY duriable I see this lasting years not months like other brands.
Cons: Sorry for me there are no cons.
