Humans are still animals. They don't suddenly become weak because they live in houses.<quoted text>
The leopard grabs you and hold with it's 10 claws sink into your flesh,your ill be in too much pain to think about pulling it's eyes out and if we try to pull it's eyes out the leopard will bite our hand and rip it off.When the leopard jumps on the human it would likely aim for the neck why bother bite the arm when you could get a 1 hit kill.
People have poked their fingers into an alligator's eyes while it was biting their arm. Sounds a handful more painful than a mere swipe from a big cat.
You're right, the leopard would aim for the throat, but if you put up your arm instead which one is going to get bitten? Anyways, leopards probably don't have the neck strength to rip out human arms, especially not from some 450 pound bodybuilder.
I'm not saying the human would win, but we are no less animals than leopards. And yes, we still have some innate knowledge of how to fight. Humans of today's world rarely (key word. Not "never") have to face predators, but nevertheless people do retain instincts.
