Bought this when it was on sale for 53.99.  Great buy!  Put it together in about 20 minutes, really easy to assemble. Seems sturdy and well built.  Bought this for my daughter's two cats, which are big cats. It looks like it's big enough to accommodate them. Can't wait to give it to them.

Pros: Sturdy and easy to assemble. Should be big enough for large cats
Cons: None
