Well actually nothing really eats a tiger. But it has been mentioned that a crocdile has been spotted killing a tiger. Also us humans are know to eat a tiger if we are hungry in the forest then we will hunt a tiger. But then again when a tiger dies or something birds eat its carry on and their meat and any there animal that likes meat will come and eat it. But most likely nthing really eats a tiger and thats why its know as tp predator.
Nothing really eats tiger , they are predators. They only way another animal would eat a tiger is if it has be killed or it has died and they eat from the carcass.
