Animal trainers use predator urine to train their animals in the detection of specific scents. Hunters, trappers and naturalists use predator urine to cover up their own scents so that animals are unaware that humans are present. Pet owners use predator urine as a training aid to teach pets to urinate in a specific place. All urines are naturally collected from domestically raised animals on farms that are controlled by appropriate state and federal agencies. The proceeds of urine sales are used to maintain the animals, thus ensuring their care and well-being.
