Don't you have to feel empathy in order to demonstrate consoling behaviour? I don't know. Just asking.
I recall documentaries in which African elephants appear to demonstrate mourning for the dead. Would this not require empathy?
I am aware of the temptations of anthropomorphism. I do it all the time with my cats. But isn't it at least possible that animals behave the way people do in certain situations because they feel the same things? I doubt cats feel empathy but there is no question that they feel love and sadness and other emotions.
