Comments about Omega Paw Cat Cozy Kingdom:

This is an excellent cat house for its price. When compared to other cat houses, however, it doesn't hold up at all. It's very flimsy - the sides and plastic supports bow out slightly when my small cat sits on the top. It's also somewhat difficult to get the plastic supports into the proper holes and staying in the proper holes. The hook part of them isn't that big. Only the smallest cat will go inside, but I can't be sure if that's because the others won't fit, or just cats being cats and having weird preferences.

It seems to be good carpeting, however, and the cats certainly like scratching up the sides and top much more than they do any of the flat scratching posts. Given its price and my economic situation, I would probably buy it again instead of waiting to save up for a more expensive model.
