I love this cat house! I just received it today, and it was very easy to assemble. It came with the screwdriver it takes to do the job. The stray cats outside love it and started using it right away. I may have to buy another one because they actually started fighting over who gets to stay in it! It's big enough for one cat (or two cats if they really like each other). It's super cute, feels very solid, and smells great. It has that yummy cedar smell! I have yet to test in the heavy rains here, but I hope it will hold up well and keep the kitties dry. I lined the bottom of the inside hidey-hole with styrofoam included in the packaging, and placed a cozy fleece blanket over it. Very good kitty hut for the price!
