A process for making an animal litter from a woody biomass starting material is described, with the performance amendments substantially located entirely on the outside surface of the woody biomass particles. The process may include the steps of densifying the biomass starting material, crumbling the densified biomass material； screening the densified biomass material for size； optionally adding a zeolite containing a scent； spray coating the sized, densified biomass particles with a surface adhesion agent； and powder dosing the sized, densified biomass particles and zeolites with a performance amendment comprising equal parts bentonite and guar gum.
