Do white tigers eat bears?

"No, tigers do not eat bears. They do not live in the same environment"

That's not true: Asiatic black bears and Amur tigers occupy much of the same range. However, tigers probably would not actively hunt bears, seeing as they are also large animals with big claws and strong teeth and jaw muscles. However, if a tiger came across a bear that was already dead, or perhaps even a lone cub, it might take the opportunity to eat it. Most likely it'll stick to deer, sheep, fish and birds.
