Provided is a litter for animals that has a reduced bulk density while retaining an advantage of a granular material containing bentonite as a main component, i.e., an ability to form a granular mass having a high strength and low height after urine absorption. The litter (2) for animals according to the present invention comprises a plurality of granular materials including a high-bulk density granular material (4) and a low-bulk density granular material (5) at a ratio by mass of 60:40-40:60, wherein: the high-bulk density granular material (4) contains bentonite as a main component； and the low-bulk density granular material (5) is configured of a core layer (6) and a skin layer (7), said skin layer (7) coating the surface of the core layer (6) and containing a binder by which grains of the plurality of granular materials are bound to each other.本發明係提供一種動物用便器砂，其不僅會保持以膨潤土為主成分的粒狀物所具有之優點，亦即能夠使吸收尿液後所形成之粒狀物的結塊形成為強度較高且較淺之優點，並且也會減低體積密度。本發明的動物用便器砂(2)係由複數個粒狀物所組成，其包含高體積密度粒狀物(4)與低體積密度粒狀物(5)為60：40~40：60的質量比，前述高體積密度粒狀物(4)係以膨潤土為主成分的粒狀物，前述低體積密度粒狀物(5)係下述粒狀物：由核心層(6)、以及用以被覆該核心層(6)的表面並且包含結合前述複數個粒狀物的粒狀物彼此之結合材的表層(7)所構成。
