Cons: Poor construction, material covering odd type of carpet.
Voted as a death trap as soon as it was put together and put in place. Took apart re-boxed and returned to store. It would have taken installing a mounted hook in our ceiling to make this safe. Even then the materials didn't seem worth the effort. A high quality piece of cat furniture I wouldn't have an issue making some modifications. This wasn't worth the trip to the hardware store.
I have other Cat Craft products that are decent and worth the price which is minimal. This model is poorly designed.
