Do any other animals eat tigers?

Tiger's are a highly predatory carnivorous animal. The answer to this question is yes, but in order for an animal to eat a tiger, it would have to be able to kill the tiger first, which is very unlikely.

Tiger's have no natural predator, but in a sense, any scavenger animal would eat a tiger that it came across that was already dead (from any number of natural causes), such as a buzzard.
