That's Animal Planet for you

A mother wolf carries a pup in its mouth. The pup is dead. She takes her pup into the bush and starts eating it. She didn't kill the pup for it died of starvation. Another pup comes along, also suffering from starvation. It needs to eat, so the mother wolf regurgitates its dead brother for the pup to feed on.

I'm watching Animal Planet. It's depressive sometimes.
