You should care, if mountain lions were like leopards, there wouldn’t be any in the US. You can put the fear of humans in mountain lions not leopards.
I read a while back about three poachers who had gone into a protected area in India or Bangladesh, at night in a flat bottomed boat. Naturally, they could have no lights (to remain undetected by the authorities) so they were going along with an electric trolling motor in pitch black on a narrow waterway with some shallow banks on each side. They heard a muffled splash, and switched on a light. There was a huge tiger on the shore, dragging one of them along by the head.
The tiger had apparently leaped through the air from the shallow bank grabbing the guy by the head in mid-flight silently plucking him from the boat without even making it rock.
My brother and I were discussing this one night, and we speculated how awful it would be if there were predators like tigers with wings. We were silent, thinking of it for a few seconds, and then both looked at each other and went “Nahh. They would be hunted to extinction. There would be no such thing in a short time.”
