I called a lion in once...big mistake. If you must, bring an extra pair of pants with you! It'll raise the hair on the back of your neck. Calling bobcats takes a lot of patience, like the others say, and I use an attention grabber to get their attention. Believe it or not, a turkey or goose feather tied to a branch or something high does the trick. Bobcats don't seem to care for the rabbit squealer; they like a bird or something squeaky...not loud. All things considered, I'd rather stick with the coyotes...
