bobcats take longer than yotes to respond. i move after 15-20 min for yotes (bow/rifle). Though they are illegal to take in IL, i have called in bobcats while hunting. Usually takes at least a full 30 min for them to respond. a decoy helps, nothing facny just a few feathers on a string and stick. keeps his attention of you. but with a gun you are always ready, bow you have to draw and wait for your shot. they are very skiddish lil critters and will spook easily.
i have called in 3 bobcats this year while deer hunting. 1 walked right under my treestand, but i had to let keep on going.
