Disgusted with changing the litter box, I reluctantly purchased the Litter-Robot. It took at least a month to convince the cats to use the new apparatus but it was well worth the wait. Emptying the litter box is a breeze. The litter lasts forever and that saves not only the cost, but dragging around heavy boxes. I use regular kitchen garbage bags which are always available. I am glad I made the purchase and I wish I had a Litter-Robot years ago.
