This cat house is beautiful.  Its super sturdy and well constructed.  Unlike other multi-tiered cat homes, each floor is suitable for "living" not just a hammock, or a ramp.  Gives the cat(s) a lot of options.  It was easy to construct, I did it myself in under a hour.  I looked and researched them all, at all websites, while this one was a little more expensive, it is hands down the best choice.
