The point of the cougar analogy is not to dehumanize anybody. It is to demonstrate that sometimes problems exist (problems as in configurations of reality that can be articulated as bad), and that doing nothing is often not the solution that will yield the greatest good in a utilitarian sense.
I'm sorry if that wasn't clear.
I'm curious, though—would you just let the cougar do its thing? Like, if that literally happened, and you were the guy at animal control who got the call?
