A litter box is a container used for indoor pets, primarily cats, to urinate and defecate in. It is typically filled with a material called cat litter, which absorbs moisture and helps control odors. Litter boxes come in various sizes and styles, including covered and uncovered options, to suit different pet preferences and owner needs. To maintain a litter box, it should be cleaned regularly by scooping out waste and replacing the litter as needed. Proper placement in a quiet, accessible area encourages cats to use the box, promoting good hygiene and comfort for both the pet and the owner.
