look on ebay for a "Wiley Coyote" looney tunes costume. go walk around in that. (obviously i'm kidding, but i imagined what this would look like in my head and it would be hilarious)

but on a serious note, these guys are on the dot. just make sure whatever you use, dead is best. make sure you rip the thing apart tho as to get the smell of blood and guts filling the air. if you're really thinking about shwackin a house cat too for bait, which i think is both f***ed up AND hilarious, just put the thing in a trapper cage alive. the sounds that cat will make being pissed off stuck in a cage with draw in a coyote for sure.
