Sani-Chips®, a long time staple in animal bedding, are manufactured from superior hardwoods. Our woods come in one of two species types, which vary depanding on which part of the country they are manufactured. The wood species are either ASPEN or a blend of BEECH, BIRCH and MAPLE. Both varieties have the same exact specifications and characteristics, only the Aspen is typically slightly brighter in color and lighter in weight. The chips are dried to 8% (+/-2%) moisture content and then screened to National Institute of Health specifications, which include a size range from 8 to 20 mesh. Our Sani-Chips® are packaged in 2.2 cubic foot, auto-clavable bags. Unlike many beddings, Sani-Chips® are ready for use right out of the bag.
