Biologists tracking jaguars in the Guatemalan jungle might smell nice but it's all in the name of science, with researchers finding the Calvin Klein cologne Obession for Men attracts big cats. Biologists Rony Garcia and Jose Moreira from the Wildlife Conservation Society's (WCS) Jaguar Conservation Program say they use hidden cameras as a primary source for observing and tracking jaguars in the Guatemala's Maya Biosphere Reserve. But they also rely on Obsession for Men, a cologne known for its complex scent, to help lure then research and hopefully ultimately preserve jaguars. The discovery was the result of an experiment by the WCS's Bronx Zoo in New York. The WCS was looking for ways to get cheetahs in front of camera traps, and found spraying the musky Obsession For Men near the heat-and-motion-sensitive cameras drew the cats for longer than other scents. They also tried out about 23 other fragrances but Obsession kept the cats' attention for longest with Nina Ricci's L'Air du Temps coming second.
