Abstract
To provide animal toilet sand that can prevent an aggregate from growing depth-wise upon absorption of liquid such as urine, and can suppress scattering. An animal toilet sand composed of a plurality of particulates mainly composed of bentonite, wherein: the particulates include smaller diameter particulates of at least 0.8 mm and no greater than 2 mm in grain size, and larger diameter particulates of at least 2 mm and no greater than 10 mm in grain size; and the particulates include the smaller diameter particulates in a range of at least 20% and no greater than 100% of the larger diameter particulates in ratio by weight. In addition, it is preferable that the proportion of the smaller diameter particulates and the larger diameter particulates with respect to the animal toilet sand is at least 90% in ratio by weight.
