Abstract: A pet litter composed of about 99.992% to about 99.998% by weight sand particles, which may be screened with a 20-50 mesh, and from about 0.002% to about 0.008% by weight of a thickener. In addition, the thickener added to the sand base to enhance the clumping properties of the litter may be digested by cats.

Abstract: A pet litter composed of sand particles screened with a 20-50 mesh or limestone in any combination with at least 2% thickener added. Additional components that may be blended with the sand are limestone particles in the size range of 0.0001 mm to 4.75 mm which clump readily when contacted by pet urine, particularly cat urine. The particle size is typically between 0.6 mm and 1.18 mm. In addition, a thickener that may be digested by cats may be added to the limestone base to enhance the clumping properties of the litter. The composition can range from 70% sand particles: 18% limestone particles: 12% thickener to 100% sand particle: 0.1% limestone particles: 0.1% thickener. A typical composition is 90% sand, 8% limestone particles and 2% thickener.

Abstract: A manual socket wrench having an adjustble gear reduction between the handle and the socket. The gear ratio may be adjusted by shifting axially a gear-carrying intermediate shaft and locking that shaft in the axial position to which it has been adjusted.
