Yes, many are. Tigers are large predators, and when their natural prey is scarce or they are injured and unable to hunt normally, they may attack humans. There have been documented cases throughout history in different regions. For example, in certain forested areas where villages are close to tiger habitats, if a tiger gets used to the easy prey of livestock and then starts seeing humans as potential targets, it can lead to man - eating incidents and thus the stories.
Some man - eating tiger stories are based on real events. In areas where tigers' habitats are shrinking due to human encroachment, like in some parts of India in the past, tigers might have turned to preying on humans out of desperation. This led to real - life encounters that became the basis for such stories.
Well, it depends. While there are historical records and accounts that suggest real instances of man - eating tigers, some stories might be exaggerated or fictionalized over time. However, the fact that tigers are powerful and dangerous animals means that the potential for them to become man - eaters is real, especially when their natural environment and food sources are disrupted.
