I MAKE THIS PRODUCT FROM THE VERY BEST FOX URINE AND QUALITY FOX GLANDS I PUT UP MYSELF. THEN I ADD A FOOD CALL. THIS SMELL IS ALL NATURAL AND IMITATES THE SMELL LEFT WHERE A FOX OR COYOTE DUG UP A FOOD CATCH. USE HALF OUNCE AT DIRT HOLE SETS, ECT. MANY CUSTOMERS TELL ME THEY GET 18 TO 20 FOX PER PINT.
