Beaphar Cage Fresh Granules utilize urine encapsulation technology to effectively trap and eliminate odors originating from used animal bedding. These granules employ a biological action with harmless friendly microbes that digest organic debris like animal urine, neutralizing and breaking down unpleasant smells. By reducing cage or hutch odors, the product also helps to deter flies and lower the risk of flystrike. A single application of Beaphar Cage Fresh Granules can keep your pet's living space fresh for up to a week. These granules are compatible with all types of animal bedding and can be used for hamsters, rats, mice, ferrets, rabbits, and guinea pigs.
