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 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 household needs. To maintain a litter box, it is important to regularly scoop out waste and replace the litter as needed. This helps keep the area clean and encourages cats to use the box consistently. Proper placement in a quiet, accessible location can also improve its usage.
