Cat litter comprising soft wood particles that are super dry and have a size range between 0.5 millimeter and 10 millimeters. The litter is made by a process of collecting, drying, separating and packaging wood particles. Waste wood material, as sawdust and wood pieces, made during the sawing of soft wood is taken from sawmills and transported to a processing and packaging installation. The wood material comprises wood particles ranging in size from fine dust to small boards. The wood particles are processed by initially heating all the particles to super-dry the particles. The super dry wood particles are subjected to a fine screening operation where the dust and fine particles are removed. The remaining particles move to a coarse screening operation where the large particles are removed in a two-step screening operation. The intermediate, or litter, particles are deposited in an apparatus for packaging the litter particles in bags. The bagged particles are sold as animal litter.
