I wash, dry, and reuse, the cheap clay litter over and over again. One 25lb bag lasts about 9mos.
Daily:
First get cat, and then poop, out. Collect in quart jars (poop, not cat).
Then scoop wet litter, and collect in a 2 gal bucket (w/ top).
Wet litter:
When full, dump into 1/4 full 5gal bucket of water with splash of amnonia added.
Mix 1 minute with a 5gal power paint stirrer and hand drill (stick will do), let it sit a bit, mix again.
Spread out on piece of loose screening with garden rake on c.3X5 raised frame tacked with hardware cloth (soil sifter).
Let rain rinse it (if it is so inclined), and the sun dry it.
Lift and fold screen to pour dry, oder free, litter into "new" litter bucket for reuse.
Compost the poop separately (by burying with leaves and dirt), and later dig back up and spread on flower garden.
