Material for treating excretion of pet

A pet excreta treating material comprising a ground material of plant origin as a main component and having a higher water absorbency in the third measurement than in the first measurement, a water absorbency of 3% to 30% by weight in the third measurement, and a specific gravity of 0.8 to 1.2 as measured before the first measurement of water absorbency, wherein the measurement of water absorbency being carried out as follows:

• an excreta treating material having been dried in a thermostat at 40° C. for 2 hours is immersed in 25° C. water for 3 seconds, and the resulting weight increase as represented by the following equation is taken as a water absorbency (%);
• The second and following measurements are carried out by drying the excreta treating material immediately after the preceding measurement in a thermostat at 40° C. for 2 hours, immersing the dried material in 25° C. water for 3 seconds, and calculating the water absorbency (%) in the same manner as in the first measurement;
• wherein the water absorbency (%)=[(weight of excreta treating material after immersion−weight of excreta treating material before immersion)/(weight of excreta treating material before immersion)]×100.
