Cats are fastidiously clean creatures, and they often prefer clean cat litter boxes. Ideally, you’ll want to scoop out a litter box every day, though you may need to clean it more often if you have multiple cats.
In determining when to toss the litter and refill the box, the answer will depend on the type of litter you use, the number of cats in your household and the number of litter boxes in your home.
For a single cat household, replacing clay litter twice a week is often the standard, while you can sometimes replace clumping litter every other week or even once every two weeks. If you notice wet or stinky litter—it’s time for a change.
Each time you empty the litter box, take a few minutes to clean the box itself. Use a mild dish detergent to scrub the box to break up any remaining litter and help eliminate smells. Make sure your cleaning products are non-toxic and approved for cats and that you rinse everything well with clean water and dry thoroughly before continuing use.
