Found this in the archives in case anyone else was wondering.
There are two basic types of lures you can make, a food/gland and a urine/gland. A quart of glands will be sufficient for a large batch of lure, at least one gallon. With the food/gland one uses a meat base which can be the bobcat itself by grinding the meat, adding the glands and other possible ingredients to enhance the formula. Added ingredients might include castor, muskrat musk, tonquin, civet, valerian, catnip, spearmint, peppermint, asafoedita, ambrette, mink musk, weasel musk, skunk musk, etc. One wants to use common sense when adding strong ingredients like mink, skunk and weasel so as to not overpower the cat glands and base that are the essence of the lure, only enhance the base by adding curiosity and rubbing enticement odors. One can preserve the meat and gland base fresh or taint them before adding sodium benzoate. Personally, I prefer them tainted. Sodium benzoate is added at about 8 ozs per gallon. One must add glycerine as an antifreeze depending upon how much is needed for the area one traps in. Glands added to the urine base would always be preserved fresh and the same enhancement ingredients would apply. Ageing the mixture for a few months really improves the end result. Good luck! Ace
