I'm pretty good at putting things together, maybe I was having a off day, but don't think so.  The inventory from paper work didn't match items I had, so I called the company.  Nice guy, but he wasn't here to put the thing together.  He did say they had had some changes in the design and parts changed, but there was no way for me to know that.  Screws etc were not in a bag, but tossed in the box, found them everywhere, even under flap of box.  Parts were not numbered, just had to keep looking at drawing and hope you had the correct part or screw.  The tree was fine after way too long and phone call to put together

Pros: its a cat tree, whats to say?
Cons: directions or lack of, different nbrs of parts compared to out dated directions
