  • Patent number: 8726839
    Abstract: A pet excreta treating material made mainly of a ground material of plant origin 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 measured before the first water absorbency measurement. The water absorbency is measured by immersing a dried excreta treating material in 25° C. water for 3 seconds and calculating the weight increase by the equation below, which is taken as water absorbency (%). In the second and following measurements, the excreta treating material immediately after the preceding measurement is dried and immersed in 25° C. water for 3 seconds to obtain a water absorbency in the same manner. Water absorbency (%)=[(weight of excreta treating material after immersion?weight of excreta treating material before immersion)/(weight of excreta treating material before immersion)]×100.

  • Patent number: 7891320
    Abstract: A pet sheet 1 including a topsheet 2, a backsheet 3, an absorbent core 41 located between the sheets 2 and 3, and a compression molded product 5 of a ground material of plant origin located between the topsheet 2 and the absorbent core 41. The compression molded product 5 is designed to swell and disintegrate upon water absorption. The compression molded product 5 is preferably designed to form a rewet barrier layer between the topsheet 2 and the absorbent core 41 as a result of swelling and disintegration upon water absorption, the rewet barrier layer being formed of water-containing bulky material disintegrated from the compression molded product 5. The compression molded product preferably further contains inorganic powder, particularly zeolite.

  • Publication number: 20090038554
    Abstract: An excreta treating material 4 of the invention contains a ground material of plant origin and an inorganic powder and self-disintegrates upon water absorption. A pet toilet 1 of the invention includes a toilet box partitioned with a drainboard into upper and lower compartments. An excreta treating material 4 containing a ground material of plant origin and an inorganic powder and capable of self-disintegrating on water absorption is put in the upper compartment, and the lower compartment has a tray 5. The inorganic powder is preferably zeolite. The particles of the ground material of plant origin in the excreta treating material 4 are preferably bound together only by a pressing force.
