Yeah, I heard one scream about 25-30 yards away as I was climbing my ladder stand in the pitch dark
and I almost fell off. I was glad I didn't have to keep walking. We have a lot of bobcats but it's
the only time I heard one. I saw him too at daylight (biggest one I've ever seen - mounted and live),
but couldn't get a shot.

A bobcat won't attack a human on purpose, I've heard a few rumors of turkey hunters getting attacked
by accident on the ground.
