I must agree with Hoser John, I trekked around Arizona desert for 8 yrs and foiled one attack by split second reaction, cat was 8 ft or less from me when I turned around. Luckily I had a shotgun and was able to fire a shot before the cat got me. Another time I was near a large boulder with a lion on top of it stalking me, observed by another member of our hunting party, and he scared it away. This animal obviously has no fear of humans which is the biggest danger signal there is regarding wild animals. Rabid, old, injured predators looking for an easy meal which may end up being someone's pet, child etc. These cats can kill an adult in about 10 seconds so don't think you can just get lucky and ignore the fact that you have a serious potential problem.
