The thing is that the Cougar doesn't need to get that close. He would have already pounced about 20ft earlier.
Not necessarily Techy, Until the deer responds the cat may just stalk. The cat is pbobably wonding why the quarry doesn't run. The cat's instinct to leap is triggered my the quarry's attempt to leave.
That not to say the pic is not fake. I'm just not sure.
