I Smell A Rabbit Here

"I am sure that a rabbit is somewhere here!"

The tiger was chasing a rabbit, suddenly it disappeared. The tiger is combing the area for its missing lunch. Will he find the rabbits hide out?

Infact, the tiger saw the rabbit, but felt pity for the poor thing. The tiger changed his mind, he didn't want to eat that rabbit, and left the place.

What could have saved the rabbit?
