This litterbox is truly awesome. Assembly could not be simpler. The quality is excellent--it is solid.  My cats took to it right away, after I took the privacy flap off, which is just held on by velcro and easily removed.   My cats dont like things like that so Im not getting the benefit of that particular feature but I didnt expect to either.  The odor control seems to be working, as well.  Great buy. I highly recommend.
