Abstract

Animal litter includes a plurality of granular materials, each having a water-shedding part and a liquid-absorbing part.

Claims (33)

1. An animal litter, comprising a granular material wherein each particle of the granular material comprises a shedding part having water-shedding properties and an absorbing part having liquid-absorbing properties;

wherein the liquid-absorbing properties are such that a mass of the granular material absorbs in three seconds 20% to 90% of a maximum absorbable amount of liquid that can be absorbed by the mass, and the maximum absorbable amount of liquid is 0.3 times to 10 times the weight of the mass.

2. The animal litter according to claim 1 , wherein the shedding part is treated with water-repellant finish.

3. The animal litter according to claim 2 , wherein the mass of the granular material has a liquid passing ratio of 50% or more.

4. The animal litter according to claim 3 , wherein the area of the shedding part is larger than the area of the absorbing part.

5. In combination,

the animal litter according to claim 4 , and

a liquid-absorbent sheet having liquid-absorbing properties for use with said animal litter.

6. In combination,

the animal litter according to claim 3 , and

a liquid-absorbent sheet having liquid-absorbing properties for use with said animal litter.

7. The animal litter according to claim 2 , wherein the area of the shedding part is larger than the area of the absorbing part.

8. In combination,

the animal litter according to claim 7 , and

a liquid-absorbent sheet having liquid-absorbing properties for use with said animal litter.

9. In combination,

the animal litter according to claim 2 , and

a liquid-absorbent sheet having liquid-absorbing properties for use with said animal litter.

10. The animal litter according to claim 1 , wherein the mass of the granular material has a liquid passing ratio of 50% or more.

11. The animal litter according to claim 10 , wherein the area of the shedding part is larger than the area of the absorbing part.

12. In combination,

the animal litter according to claim 11 , and

a liquid-absorbent sheet having liquid-absorbing properties for use with said animal litter.

13. In combination,

the animal litter according to claim 10 , and

a liquid-absorbent sheet having liquid-absorbing properties for use with said animal litter.

14. In combination,

the animal litter according to claim 1 , and

a liquid-absorbent sheet having liquid-absorbing properties for use with said animal litter.

15. The animal litter according to claim 1 , wherein the area of the shedding part is larger than the area of the absorbing part.
