The days of kitty litter may be numbered.

So. Calico has never really had any problem using the great outdoors as her toilet, but until recently, Biscuit has always come inside to use the litter, then gone back outside. However in the last week, mostly due to Darrin dumping some used kitty litter in a corner of the yard, Biscuit is learning that it's okay to do it outside, too. So we're down to one litter tray in the laundry room now, and we've been letting the cats out briefly in the mornings so they can do their business. All means less stink in the house and less money spent on litter, both very good things.
