I've called up bobcats twice.
First time I had a strutter deke with hens set out. A mature bobcat came in, sat down and stared at my dekes. He seemed to be sizing them up, but thought the better of it and walked away.
Second time I had a juvenile bobcat come in from behind me. He passed within 10 feet of me. Got about 10 feet from a decoy, then chickened out and ran off. Maybe he figured he was gonna get a butt whippin?
They were both very cool experiences.
