Traditional Cat Litter

Clay cat litters are the oldest type of commercial cat litter and are still widely available. Clay is used in cat litters because of its ability to absorb liquid. Traditional clay litter can absorb its weight in cat urine and, because it separates the urine effectively, has some natural odor control as well.

However, as clay litter becomes soiled and can no longer absorb liquid, odor can begin to be a problem. Various ingredients such as baking soda and charcoal may be added to the cat litter to help with odor control.

Traditional clay litter must be cleaned and changed often. These litters do not form clumps that are easily removed with a scoop, so normally the entire litter box must be emptied, cleaned, and the cat litter replaced at least once a week.
