Try Scoop Away Clumping Litter

The previous solution covers the subject well. I will only add one comment: I'm not a spokesman for this product, but I have found that Scoop Away is by far the best clumping litter. Sometimes my cats get lazy and don't cover their "product," and Scoop Away leeches the odor very well; likewise, for the urine. You can even skip a day of cleaning. I have tried many other litters, but regret spending the money, even when they cost less.
