Cat litter needs to be replenished and replaced periodically. The specific method depends on the usage of cat litter, the number of cats, and the cleanliness of the litter box.
When the litter box gets low, add more litter to ensure your cat has enough. Also, to keep the litter box clean and hygienic and prevent excessive waste buildup, change the litter regularly. If you only have one cat, change the litter about once a month.
