Shake-Away Coyote/Fox Urine Granules are an effective, natural, and non-harmful product used for repelling domestic feral cats, and more from using your lawn, flower beds, and gardens as their litter box. This product takes advantage of the Predator-Prey relationship, specifically the prey animals genetically programmed instinctual fear of being harmed. Simply spot-treat the general activity area twice a week for the first two/three weeks and then twice a month for maintenance. Over time this will significantly reduce and eliminate pest activity.
