Choosing the Best Cat Litter and Accessories
Cat litter works by absorbing cat's urine and covering feces to reduce the growth of odor-causing bacteria. Most cats do fine with an unscented, clumping kitty litter, but some consumers prefer scented litters as the best option. The two main categories of litter are "clumping" and "non-clumping."

Clumping litter sticks together where a cat urinates, making it easy to scoop clumped litter and solid waste out of the box every day. Clumping litter does not need to be replaced every week. Just add more litter as the level gets low from scooping. Every three to four weeks, replace the litter entirely and wash the litter box.

Non-clumping litter is made from natural clay, and dried into granules, it is available in unscented, or with additives such as baking soda, and scented fresheners. Scoop out solid waste every day, but once a week the entire litter box should be emptied, washed and replaced with fresh litter. If excessive urine is not absorbed and seeps to the bottom of the box, it may be necessary to replace the litter sooner.

Filling the Box

The litter layer should be at least two inches deep in the box. This makes cleanup easier and gives the cat enough litter to scratch in and bury waste. Plastic litter box liners make the cleanup easier, and can be used with any type of litter.
