I was skeptical about buying a wooden cat house, but so far this one has held up. It smelled like strong paint when we put it together (with a drill), but it smelled fine after it aired out a few days. I did get some of that cabinet liner and put it on the inside shelves so that it could be wiped down easier because it’s unrealistic that wood can be cleaned. I got it for a couple of stray cats we’ve been trying to get fixed, and neither has slept in it yet but the one we got fixed recently has hung out in the top feeding area enough to make me think she might when it’s cold. It isn’t insulated, but I plan on putting a heating pad from our old KH house in it with the blanket and that may be enough when it gets cold. The only complaint I have is the entrances are super small and not big enough for a bigger cat to crawl through.
