Suppose there is a movie in which the heroine is liked a lot by animals (as a means of foreshadowing how lovable she is to people).
Would they use an actress or actor that is naturally well-liked by animals, or conversely use animals that happen to like this character?
Can animals be trained (e.g. through Pavlovian conditioning) to like a particular actress, or conversely, can a human being be trained to make herself likable to animals?
Are there drugs, scents or other stimuli that can used to make an animal like a person?
Which of these methods (or others) are used to get animals to like a particular character?
