Claims6
A method for removal of animal waste, comprising:
- providing a container including an animal litter, said animal litter comprising:
- a sorbent comprising at least about 10 weight % finely ground pine wood powder, wherein no more than about 0.5% of the pine wood powder particles are larger than U.S. standard #10 mesh screen size, no more than 30% of the pine wood powder particles are larger than U.S. standard #20 mesh screen size, and at least 20% of the pine wood powder particles are smaller than U.S. standard #20 mesh screen size;
- a lubricant;
- and
- a cohesiveness agent, said cohesiveness agent comprising a starch;
- said animal litter being in the form of discrete plural compacted particles which tend to agglomerate when wetted,
- said cohesiveness agent being present in said litter in an amount effective to enhance the intraparticle cohesion of said particles,
- allowing an animal to excrete waste into said litter, whereby liquid present in said container as a result of said waste causes at least a portion of said litter to agglomerate into at least one clump;
- and
- removing said clump from said container.
