I've had an old carpeted cat condo in my living room for nine years and decided both the cats and the living room could use an up grade. The box was very heavy, I had to drag it in the house. The quality was apparent from the moment I took the pieces out of the box and the fact you are able to get replacement parts made this one the smart choice.  It's plenty large for three cats and I mean three adult cats. So many condos look nice but they don't always build them to accommodate adult cats. This one has plenty of room for my ten pound cats that like to sleep in the little houses. Well built and stable I would recommend this piece of cat furniture.

Pros: Well built, sturdy and stable
Cons: The tools they include are pretty lame
