Those Chinese bile farms aren't a very well kept secret, but the idea of a bear killing its own cub out of mercy, and then committing suicide by smashing its head into something is absolutely ridiculous. It frightens me that people actually believe that.
Exactly, I can see the momma bear accidentally killing its cub trying to free it, I can see momma bear running into a wall or door trying to get out or free itself. But I cant see momma bear kill its cub, out of mercy to save it from the torture and then killing itself too. Its a believable story to the people who try to humanize animals, their thoughts and feelings though.
