I've only called in 3. Two on a jack-rabbit sound using a (Tally-HO), 1-on a cottin-tail sound using a(Carlton's Predator Call). IMO, if their in the mood; hungry, curious, territorial ect. They'll check out many sounds. In Iowa coyote's hate, racoons and cats. Last winter, I came across 3-coon killed by yotes. They didn't eat them. A farmer friend, told me they come up in his yard, and killed his neighbors tom-cat. They then ran off with him.
