Psychology people explain why humans like to feed creatures
As mentioned in your tag OP, there's is definitely an urge factor. We are social animals surving and thriving through bondings and affection. So feeding others is a conscious/unconscious nonverbal way of showing to someone yor care, affection and to initiate intimacy. Food also is a basic need in Maslow's hierarchy, a necessity hence it's also a relatively proven manipulative tool in terms of establishing positive reinforcement and control over a living being.
Hope my explanation made sense ^-^
