You guys are Master Grammatorians, correct?

I feel like I've asked this before, but I feel like I must ask it. I know the difference between "that/who" in the case that is a common mistake. That part is easy. And I know that "that" is for non-humans. But what happens when the object is given human-like characteristics? Not necessarily full-on anthropomorphism, but just little things like intelligence or possibly communication. Would the rule of "that" for inanimate objects be adhered to when you're talking about the desires of a plant or animal? Would this be a gray area where either word could be appropriate depending on the speaker's choice?
