granules of the particulate matter have an average pH of no more than 12;

the particles include an inorganic porous material; and

an inorganic binder, which binds particles together, and a pozzolanic material

wherein the inorganic binder includes a non-cement solidifying agent, and

wherein the inorganic porous material comprises at least one member selected from the group consisting of zeolite, attapulgite, sepiolite, diatomite and diatom shale, and

wherein the pozzolanic material comprises silica gel

wherein the content of the pozzolanic material in the particulate matter is 5 to 15 percent by mass, and

wherein the plurality of particulate matter is subjected to a water-repellent treatment.

6. The animal litter according to claim 1 , wherein a content of the inorganic binder in the particulate matter is 5 to 30 percent by mass.

7. The animal litter according to claim 1 , wherein the particulate matter includes a fragrance.

8. The animal litter according to claim 1 , wherein the particulate matter has an average strength of no less than 30N.

9. The animal litter according to claim 1 , wherein the particulate matter has a cylindrical shape of 4 to 7 millimeters in average particle diameter and 6 to 15 millimeters in average particle length.

10. The animal litter according to claim 1 , in combination with a litter container and an absorbent sheet for absorbing liquids wherein
