Fifty million people died in the WWII, the biggest massacre in the history of humanity. But the animal kingdom also paid a heavy toll, despite no official numbers being compiled for the victims. This included combat animals, animals that backed up humans, those that entertained or consoled them, some that fed people, and other animals that were symbols.
