All around great product. I have two three year old cats, one weighs 13.3lbs and 12.2lbs for the other. This cat house is sturdy and holds up well against their constant play and lounging. 

I'd recommend this to anyone looking for an inexpensive way to keep cats entertained. I love that Kitty City came out with this new and improved product. I owned the earlier model of this cat house and it was great for two years I can already tell this model will last even longer.
