Abstract: An animal bedding mixture is disclosed herein. The animal bedding mixture includes a bedding material and a bedding material additive. Bedding material is preferably straw, sawdust, sand or recycled manure solids. The bedding material additive is preferably 60-99% by weight absorbent clay powder, 0.1 to 35% by weight chlorite salt, and 0.01-35% by weight sodium bisulfate or sodium percarbonate. The bedding material additive of the present disclosure is inert when dry and neither germicidal or acidic. However, when the additive is exposed to moisture, such as animal urine, the sodium bisulfate will acidify the liquid, causing the formation of hypochlorous acid and chlorine dioxide. Hypochlorous acid and chlorine dioxide are very powerful, broad spectrum germicides that have proven efficacy against E. coli, Staphylococcus aureus, and other micro-organisms commonly found in animal bedding.
