I'm in the middle of putting this together. I wanted to show you that the easiest way to put it together is put the dowels on first on one side then slide it on. from what I can figure out, I really like it. it was really a good deal. it's really much bigger than I expected for what I paid. it's really nice. I hope my cat loves it and it actually came with everything, including an angle iron. don't over tighten the screws. it'll strip out the dowel and make sure you get the right side up on the mat because one side is down and the other side is up and they include some catnip which is really a nice touch. it all came in a very nice ziplock bag in a nice box, very nicely packed in a plastic protective shipping bag on the outside. very nicely taped good around it. they actually use the label as part of the tape to tighten it even more to protect the box. the cat scratcher it's really pretty
