Patent ID: 8726839

Claim:
A pet excreta treating material comprising a ground material of plant origin as a main component and having the following properties: (1) a higher water absorbency in a third measurement than in a first measurement, (2) a water absorbency of 3% to 30% by weight in the third measurement, and (3) a specific gravity of 0.8 to 1.2 as measured before the first measurement of water absorbency, wherein properties (1) and (2) have been measured as follows: the pet 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.
