I've called a lot in cottontail country and never saw a cottontail come into a call. I've called jack rabit country and had a couple come into a set in thick cover and there was usually a coyote along soon afterwards and just assumed the coyote flushed it through the set. I've also called in areas that were thick with jackrabbits, they would scatter all around you going into a stand and never had a jackrabbit respond on it's own.
