I've read that humans are able to empathize with other humans, to feel as another person does, through mirror neurons. I'm guessing that they're able to empathize with primates too, as they share similar brains, have similar limbs, faces, etc. So, when someone watches a monkey or child drink juice, they can empathize some of the joy of drinking juice.
But what about a human empathizing with less humanoid animals? Can a person who has developed a personal bond with say, a horse, 'feel' the same way as the horse does? Can one understand the joy of a cat eating its favorite food?
Do mirror neurons apply between humans and animals as well?
