One of the most heatbreaking pictures I've seen. From National Wildlife Federation.

32. Do you have a link? Is it the same polar bear?

Yes, polar bears will eat their dead. Male polar bears are likely to hunt down cubs if they are hungry enough.

And animal mothers are known to eat their dead offspring. That offspring represents a lot of energy and resources that would go to waste if the mother let it simply rot away.

It does not make the grief nonexistence. Did you ever wonder what instincts feel like? I think instincts feel like emotions feel. So I do not believe animals do NOT feel emotions. They just don't remember them as long as humans do.

I once saw a nature show were a mother lion hunted and called for her dead cub for weeks. She eventually died because she would spend all day looking for her long dead cub and did nothing else. It was instinct that drove her to search for her cub. But how do you know that her instinct did NOT feel like emotions feel to humans?

I think humans, especially those who have not been around animals much, overrate their own emotions as if they are somehow special and unique to humans only. Animals do feel emotions, what's so special about that?
