Beaphar Cage Fresh Granules are a revolutionary product, using urine encapsulation technology to trap and destroy smells that arise from used animal bedding. The granules provide a biological action, using friendly-microbes which are harmless to pets and people. The friendly-microbes work by digesting organic debris such as animal urine, and help to neutralise and break down odours. Reducing the smell around your pets cage or hutch will also help to decrease its attraction to flies and reduce the risk of flystrike. Just one sprinkling of Beaphar Cage Fresh Granules will keep your pets cage or hutch fresher for one week. Beaphar Cage Fresh Granules are suitable to be used with all types of animal bedding.
