ISO-Pads represent the next generation of bedding materials. They are flat, compressed, rectangular pads of cotton fiber material that can be conveniently dropped into standard shoebox rodent cages that are meant to be used as a contact bedding. Rodents enthusiastically shred the pads into a soft, fluffy consistency which offers an unsurpassed enrichment aspect to this unique bedding product. ISO-Pads are perfect for post surgical applications as the bright white pad offers great visual monitoring of leaking and bodily functions. Eliminates variables associated with recycled or synthetic bedding products. Produced from FDA-approved, cotton-based cellulosic fibers that are hypoallergenic. Absorbs more than 400% its weight in water. Controls odours better and lasts longer than traditional bedding materials. 6" x 10" (15.24cm x 25.4cm) Cotton Pads. 500 pads per case.
