I don't use cat litter any more. One day, I got the bright idea to put a dog disposable pee pad in the litter box to help with cleaning. I only put a couple of cups of cat litter in the cat box. I gradually reduced the cat litter over a two week period. Now, I only use the pee pads. I love the Hartz lavender scented ones. I have no cat litter odor and no tracking of litter. I change the pads twice a day. Since they are plastic lined underneath, all I have to do is pick them up and put them in the trash.
