You can buy several types of pee, as a powder or in the original liquid state. For example:

Predatorpee 100% Wolf Urine is a powerful communicator to animals at the top of the food chain. Coyote, Moose, Bear, Elk & Mule Deer fear the wolf more than any other animal. That is why the scent of WolfPee is so effective. When these large prey believe there is a wolf in the immediate area, they flee. By liberally marking an area with WolfPee, you duplicate the territorial marking habits of wolves in the wild. This illusion triggers an instinctive response in the prey. If wolves are around, these animals want to be far away! Predatorpee is not a pesticidal repellent, but rather it is an extremely effective territorial deception scent. The same territorial marking attributes, also make WolfPee an excellent training aid for giant breed dogs. Dogs react to the illusion of canine territorial encroachment and will instinctively respond by marking over wherever WolfPee has been applied.
