...i used to use catfish stink bait and a large piece of denim to laydown around where i'd set the onida jump trap..... that stinky stuff really brought em in out in west texas , and covered the human scent . and believe it not - a portable cassette player playing the wounded rabbit sounds worked for coyotes and bobcat. i was sold and labeled a a predator call. i actually have been seeing more bobcat that coyotes on the outskirts and under-development areas around fort worth the last two years. back in those trapping days , a coyote pelt could bring $40-60 bux. they were in demand over in europe (early 1980's).
