The yellow rat snake that may enjoy some human contact.

I think it's fair to say most/if not all animals experience fear, which is technically an emotion... And it's useful in self preservation (generally speaking... We all know what deer in headlights refers to but there will always be exceptions to the rule). Of course I'm no scientist but it is something to at least consider...

And my apologies if I'm repeating something already mentioned.. Saw the multitude of grumpy responses and didn't feel like risking having to sort through 8 pages of that.. I'll take a proverbial back hand for being lazy and sticking my nose in here after the fact because I felt like it.
