I was calling predators one time, sitting against a tree in a creek bottom.  It had been around 30 minutes or so, and no action.  I was just getting ready to leave when I heard the squirrels start to get agitated, so I sat back down.  When I looked towards the creek I saw a bobcat sneaking towards me, then another, and another.  In a few minutes all 3 were within 10 feet of me, and one was about 5 feet up a tree looking down at me.  I'm not sure why I waited so long to shoot, but as soon as I moved an inch there were bobcats flying everywhere.  Needless to say, no animals were harmed!
