Really? I have not heard any accounts of bobcat attacks. I know they fight like hell if cornered, but scratch, claw and bite, not deadly back of the neck type attacks. We used to believe that mountain lions would not attack people but now that they are no longer hunted, they will on occasion. I have never heard of an attack on a human for purposes of predation, and I have never heard of an attack being successful.
The ones around here are pretty small, but I have seen pictures of the ones from Canada, and they are quite large. I could see those kitties being dangerous.
