Litter wizard system granules are an aggressive, non-toxic product specifically designed to absorb odor causing ammonia gasses, keeping your cat's litter box or pet's cage odor free. Ammonia gasses, found primarily in urine, are the source of that foul odor that takes over the homes of cat owners. The granules are the true science of the product system that enables it to deliver superior results. The granules are formulated with naturally occurring ammonia eating microbes that continue the process of digesting excess ammonia that litter can’t absorb. The microbes make their way into the pores of the litter box plastic creating another layer of powerful odor absorbing protection against residual urine and feces that often collect on the bottom of most litter boxes. Litter wizard system granules are easily mixed into your cat’s litter, which immediately work to eliminate high ammonia levels that cause odor and upper respiratory disease. Granules are packaged in a 8-pound resealable zip lock bag. Litter wizard system delivers maximum odor control when used in conjunction with the litter wizard system cat litter box odor deodorizer spray available in 8, 16 and 32-fluid ounce bottles. Quick and easy to use, just follow the manufacturer's use instructions for optimal results.
