By combining micronized resin or adhesive agent of which the main ingredient is silica sol to silica gel powder and compressing and molding, a litter which has superior absorbency and deodorization capabilities, does not roll nor spread over a wide area easily, does not easily stick to the bottom of animals' feet, and is not easily carried out of the container when an animal enters or exits a container holding this litter can be provided.

Abstract: An animal litter box is to be provided that can be cleaned easily and can reduce the number of time to change an animal litter, particularly an animal litter box that allows liquid such as urine evacuated onto the granular materials to move to a liquid-absorbing sheet efficiently. An animal litter box includes a granular material container having an opening for an animal going in and out, and a liquid penetrating bottom part on which granular materials are dispersed; and a liquid-absorbing sheet holder placed under the bottom part of the granular material container on which a liquid-absorbing sheet is placed, wherein the bottom part of the granular material container has a liquid leading part formed by connected arches on a side facing the liquid-absorbing sheet.

Abstract: Disclosed is a pet sheet including a backsheet, a liquid-permeable topsheet and a liquid absorbent layer which is smaller than the backsheet and disposed between the backsheet and the topsheet. The backsheet extends beyond the liquid absorbent layer to provide side regions outside the liquid absorbent layer. A hydrophilic sheet is provided above the backsheet in the side regions.

Abstract: Disclosed is a pet sheet including a backsheet, a liquid-permeable topsheet and an absorbent core disposed between the backsheet and the topsheet for absorption and retention of liquid. The absorbent core is a pulp layer mixed with a first superabsorbent material. A second superabsorbent material is disposed in a spaced pattern between the absorbent core and the topsheet. The first superabsorbent material has a faster liquid absorption rate than the second superabsorbent material.

Abstract: The present invention provides a diaper for a male pet which is not displaced even when the diaper is fitted on a male pet for a long time and can cover a urethral opening of the male pet and can surely capture urine or the like.

Abstract: The present invention relates to an animal litter for using an animal litter box and a litter box using the same. The animal litter can suppress odors generated from animal excrement evacuated on the animal litter. The animal litter is comprised of a mass of grains having a peculiar liquid passing property whereby most part of liquid poured onto the grains is not held in the grains but passed through them meanwhile other part of liquid remained in the grains is absorbed into the grains. More concretely, the maximum absorbable amount of liquid of a grain is 3 to 4.0 times the weight of the grain, the amount of liquid absorbed by a grain per three seconds is 20 to 70% of the maximum absorbable amount of liquid absorbed by the each grain; and a liquid passing ratio of the mass of grains is 70% or greater.

Abstract: An animal litter box system that can be used for a long time about 3 to 10 days and can prevent the occurrence of undesirable odors is to be provided, particularly to provide a liquid-absorbing sheet used for the animal litter box system. A liquid-absorbing sheet used for an animal litter box is characterized by comprising an antimicrobial and bacteriostatic part having both an antimicrobial property and a bacteriostatic property; or both of an antimicrobial part having an antimicrobial property and a bacteriostatic part having a bacteriostatic property.

Abstract: A shadow mask with a slot having a substantially rectangular shape and a curved slot. The rectangular slot is composed of a back side opening formed on an electron beam incident side, a front side opening having a large area to allow the electron beam to pass, and a side wall sections inclining between the back side opening and the front side opening. The curved slot is composed of a back side opening (11) formed on the electron beam incident side and curved such that both longitudinal end portions are apart from an axis of ordinate passing a central portion of the shadow mask, a front side opening (2) formed having a large area to allow the electron beam to pass and side wall section (3 - - - 6) inclining between the back side opening and the front side opening.

Abstract: A pet sheet includes a hydrophilic top sheet arranged on the absorbing material, wherein a flap which is formed at least adjacent a peripheral edge of the absorbing material and opens toward the center of the absorbing material. The flap has an upper surface of hydrophilic.

Abstract: A pet sheet includes a hydrophilic top sheet arranged on the absorbing material, wherein a flap which is formed at least adjacent a peripheral edge of the absorbing material and opens toward the center of the absorbing material. Urine, which is not absorbed in the absorbing material and flows on the hydrophilic top sheet, enters between the hydrophilic top sheet and the flap, and can be stopped there.
