Are tigers cannibals?

Tigers are predators that eat meat. While I don't know of a specific instance of one tiger eating another, it's not impossible.

Generally speaking, tigers would much rather hunt deer or rodents, since they don't fight back as much as another tiger would. But, if all other food sources were gone, and a tiger was faced starvation, it would definitely consider attacking another tiger and eating it to survive. Such an event would be the very last resort when no other options were left before death.

So to be specific, tigers are not "cannibals" since it is not something they would do normally. The situation would have to be very extreme.
