This litter box is genius!  It neatly and calmly moves "the stuff" off to the side, under a little covered area.  The crystal litter itself is amazing and I did not smell the cat box at all.  Normally, I clean their box every night normally and it almost made me believe I could skip it occasionally, though it would depend on how many cats you have.  Mine needed to be changed in just over a week, not the time stated on the box, but every cat is different.  This would be a great gift for any cat lover.
