Totoe, time to try some calling. I think it is best to use high pitched calling tactics, such as wood pecker in distress of cottontail distress works well too. Bobcats generally speaking, don't have too big of a home range, so chances are, you should be able to find this cat again. They like brush piles, are there any around or near the area you saw the cat? Set up to call just like setting up to call coyotes, but stay put for thirty minutes, he may show quicker, I've seen cats show up in just a couple minutes of calling before. They will not come running in, like a coyote, they will come slow, usually sneak in, so keep your eyes peeled, and listen for squirrels or jays, they will often tell you that something is in the area. An awesome video to see bobcats being called in, is the new Verminator video. On it, you'll see that cats often get to where they can see the sound, and will simply sit down, and not come any closer. And if you get busted by bobcats, they usually won't run away, they will try to sneak away just like when they come in. Good luck!!!!
