The cat's out of the bag about a new use for cell phone ring tones. They're being used in India to lure and trap leopards that are wandering into human settlements, according to Reuters.
The ring tone sounds of cows, goats and roosters trick the cats into believing there's an easy meal inside the trap.
The leopards are transported far away from the villages and released, according to The Associated Press.
Wildlife activists like the idea. They say previous methods involved pits in which the big cats could get hurt.
