Abstract
The animal litter comprises a cellulose litter material that contains a pheromone-like attractant substance which makes the litter attractive to animals seeking a place to defecate and/or urinate. The litter material is pelletized to give the litter a consistency comparable to that of fine gravel. The pellets formed from the litter material hydrate slowly but positively and are disposable in water. The density of the pellets is such that they retain their structural integrity on hydration. The pellets are formed from ground paper which has been moistened with sufficient water to hold the particles together but not so much as to cause the pellets to feel moist. An acid salt may either be added in the water or as a dry powder to the ground paper. This salt carried by the water in the pellets neutralizes the animal urine (and the ammonia-like compounds formed from it) while maintaining the pH of the litter at a level acceptable to the animals. A pheromone-like attractant substance is added to the pellets either with the water or by spraying it on the finished pellets. A further step comprises compacting the saturated, ground paper into pellets having the previously enumerated properti…
