Do my cats love this? Love would be a profound understatement. I have 4 cats and they have all found their own favorite areas of this cat tree. My oldest guy, though, pretty much refuses to leave the tree and takes turns sleeping in all areas no matter how small they might be for him. It’s been pretty entertaining for everyone involved. Some of the areas were a little smaller than I expected but that hasn’t bothered anyone. It was easy to put together - LOTS of parts though. Overall I 100% recommend!
