Most sources consider animals as separate from humans, so non-animal would mean human. In general poor treatment of animals is considered a lesser offense than one commited against a human, as an illustration of the separation of categories.

Being that we are animals, this trait is not restricted to humans. Animals don't observe much when another type of animal huts a different animal but may come to the defense of its own kind, if related.
