Abstract
An animal litter box is to be provided that can be cleaned easily and can reduce the number of time to change an animal litter, particularly an animal litter box that allows liquid such as urine evacuated onto the granular materials to move to a liquid-absorbing sheet efficiently. An animal litter box includes a granular material container having an opening for an animal going in and out, and a liquid penetrating bottom part on which granular materials are dispersed; and a liquid-absorbing sheet holder placed under the bottom part of the granular material container on which a liquid-absorbing sheet is placed, wherein the bottom part of the granular material container has a liquid leading part formed by connected arches on a side facing the liquid-absorbing sheet.
