Animal Morality.
Are you one of those who believe animals don't possess moral behaviour?
Definitely, animals can tell right from wrong.
Even though the moral nuances of particular species might vary, they are certainly there.
What's interesting is that the moral judgement was from one class of animal to another, not even animals of the same family.
