Is there anyone among us who does not think that they have discovered a better/best way to do something? If hefty credentials in the chosen field give weight to an "opinion", I would like to begin by stating that I have five cats. I think that equates to a PHD in litterboxocolgy.
Store bought litter has two inescapable problems: the cost and the tracking throughout the house. Old newspaper eliminates both issues (not an intentional pun). Use one section unfolded so that one page at a time shows on the bottom of the litter box. Place a second folded section on the bottom. Keep some folded sections nearby and add them on top if you want later. To change all you need to do is roll the long bottom section starting from the exposed and still clean top of the page. It takes seconds and costs nothing.
So if this blog is not up to the usual meaty, intelligent discourse you expect form me be glad I did not include pictures.
