Such a great product!
I've used KPC for several years now. It cuts off the smell, the clean up is so easy, scoop two times each day and then once a month bag up the old cat litter, recycle box and done. Open, unfold, set up, new box, shoo cat helper out of new box :-), pour new cat litter in, set it in its space and wait for kitty approval to come. Both cats love it!
