Animals do not necessarily repay the favor in the way humans would normally understand it. Although tigers are very mysterious and majestic animals, they do not have complex emotions and moral concepts like humans, so saving a tiger does not mean that they will actively repay the kindness.
However, it is worth mentioning that in nature, wild animals often help or cooperate with each other to survive. For example, predators such as lions, leopards and tigers may team up to hunt when faced with larger prey, while some birds assist other animals in removing parasites from their bodies.
Therefore, even if we cannot expect wild animals to directly reciprocate our kindness, we should still respect and protect them and coexist peacefully with them. For humans, protecting wild animals and the natural environment itself is an ethics and responsibility.
