Abstract
A particulate non-clumping animal litter composition is disclosed. The composition comprises non-clumping absorbent particles bound to magnetically-attractable metal particles such that substantially all particles of the animal litter composition are attracted to a magnetic surface. The animal litter composition exhibits favorable properties such as absorbency, resiliency, homogeneity, and particle size. Methods of production for non-clumping animal litter compositions are also disclosed that employ sufficient shear to bind the non-clumping absorbent particulate material to the magnetically-attractable metal particles such that the animal litter compositions exhibit favorable properties. A method and apparatus for the collection of magnetically-attractable animal litter particles are also disclosed.
