R-P only buys the very best urine on the market. As you know, urine is always used by the trappers who make the bigger catches. Many trappers use pure urine only with their sets, while others make big catches with urine, bait & lure. Urine is a must for canines. Bobcat & Raccoon also respond to urine. Coyote and Bobcat urine is also good to use as a predator scent to keep deer and rabbits out of your garden.
