I think the cat tree top. For the price you get such a big tree in any pet store. It was built in the blink and from me. I am totally technically inept and actually let build everything from my father. The scratching post is very stable. My two cats love it. You constantly rush up and down and scramble it. The scratching post wankelt not even correct. Even my 4 year old daughter is once climbed. Even that has endured the tree. And the cat tree did not stink. Of course he has "new" smell when unpacking, but that's all stuff like that. My cat could hardly wait until it was set up. So he can not stink. We are very satisfied. Thank you.
