Review on Large Cat House For Cats & Kitties - Petique Feline Penthouse Three Level Cardboard Kitty House by Mike Sevenfourgd

I purchased this for my two 4 year old cats and it was very easy to assemble. They love it. I put it next the window so they can see the birds outside from the top level. It is surprisingly sturdy for cardboard and can support their 11 and 12 lb weights easily. I wish I had gotten this for them as kittens. They seem to love the top and bottom levels the most and they love it when I thread pipe cleaners through the walls to play with. Overall a very good product.
