With three cats, it's important to have good litter. I've tried crystals, clay, scented and unscented. I've settled on Boxiecat... It's unscented but absorbs odors, clumps well, and there's very little dust. Best of all, the stuff seems to last forever. I just pour in a little from the bag every few days. There's no need to completely clean the litterbox every couple of weeks. Instead, I do a full dump-and-scrub every couple of months.
