What is Litter box?
[[Image:Catfiller.JPG|thumb|220px|right|Cat using a litter box]] A '''litter box''' (sometimes called a '''sand box''', a '''litter tray''' or a '''litter pan''') is a place for [[cat]]s and some other [[pet]]s to use as a [[toilet]]. Litter boxes usually need to be [[hygiene|cleaned]] regularly. Cats, for example, wish to have their box cleaned every two to three days. Some cats create litterboxes in places like [[playground]]s and [[sandpits]]. Litterboxes usually produce bad smells, which can be avoided by special litter. Many people buy a special kind of [[clay]] to fill the box, for this reason. {{biology-stub}} [[Category:Pets]]
