I accidently called in a bobcat last august while bear hunting out of my tree stand with a bow. I dont know anything about predator calls, but remembered I had my buddies rabbit squeal call in my back pack. So I blew on that for a little bit till I lost interest in it.
About 20min later I heard a stick break, and sneaking hrough the ferns was a bocat. He jumped up on a log about 30yds away and just stared at the bottom of my tree.
A couple days later and I would have been able to take a shot

Now that deer is over I'm going to try some predator hunting. Ayone hunt with a tree stand for coyote/bobcat?
