However, there are a few things to consider:
* Humans are the biggest threat to tigers. We hunt them for their body parts and destroy their habitat.
* Other large predators, such as lions or bears, might occasionally scavenge on a tiger carcass, but they wouldn't actively hunt them.
* Diseases and parasites can also be a threat to tigers, especially when they're already weakened.
So while no animal specifically hunts tigers, they are certainly vulnerable to other threats.
