Depending on the litter material, you may need to change the cat litter more often. Nowadays, there are a lot of options of litter to choose from, and before grabbing one in the store, the most important factor to consider is how frequently you can clean the litter box.
Probably the most common litter type, clay litter is among the options you have for your cat's box— they can be non-clumping or clumping. They both have advantages and disadvantages, but the non-clumping one requires more frequent replacement. Cats generally prefer this type due to its resemblance to the soil (where cats naturally poop/pee). On the downside, this is the messiest, not to mention high-dust/high-tracking on the paws. Clay litter requires weekly replacements— or even more often. And although it's cheap, the maintenance and cleaning it needs may be quite a price to pay.
If you have concerns about your pet's litter box habits, make an appointment with your veterinary hospital Chesapeake, VA.
