A cellulosic particle, especially useful as a cat litter, is manufactured by agglomerating a fibrous cellulosic feed material in the presence of water, compacting the surface of the agglomerated particles, and drying the particles.

Robert C Sokolowski, Russell L Johnson: Particulate paper product, especially for use as animal litter. Kimberly Clark Corporation, Gregory E Croft, Donald L Traut, Jeremiah J Duggan, October 28, 1986: US04619862 (61 worldwide citation)

Discrete absorbant particles, useful for example as an animal litter, are produced by joining together layers of formed paper pulp, the layers being compressed together in such a way as to remain together under normal use conditions, prior to immersion in water, but so as to wholly or partially sepa ...

Robert C Sokolowski: Elasticized non-woven fabric and method of making the same. Kimberly Clark Corporation, Joseph P Harps, March 29, 1988: US04734311 (38 worldwide citation)

An elasticized non-woven fiber material is made by combining one or more textile fibers with one or more elasticizeable fibers and bonding the combined fibers together. The resultant web of bonded non-woven fibers is then heat-treated to heat-shrink the elasticizeable fiber and recover its elasticit ...
