When the Bronx Zoo was trying to get their cheetahs in front of camera traps, an experimental test found that the animals were drawn to Calvin Klein's Obsession for Men, and now biologists tracking jaguars in the Guatemalan jungle have followed their lead. The Wildlife Conservation Society's (WCS) Jaguar Conservation Program uses hidden cameras as a primary source for observing and tracking jaguars, and rely on the cologne's complex scent to lure their subjects, according to Reuters. While there's no success rate given—though they plan to expand the use of the cologne in their studies—we're guessing it's similar to the Sex Panther scent by Odeon: "60% of the time, it works every time."
