Biologists can't speak on the effectiveness of Calvin Klein Obsession for Men on the cougars at your local bar, but they do know that jaguars love it. Rony Garcia and Jose Moreira from the Wildlife Conservation Society's (WCS) Jaguar Conservation Program use the cologne to attract jaguars in the jungles of Guatemala. "The method we are using to study the jaguars here in Guatemala is a non-invasive method which is based on photographing the individuals by using camera traps," Moreira says. "It has been very useful using Obsession (for Men) to get the jaguars in front of these camera traps ... and that allows us to estimate with greater confidence the genders and the numbers that live in each studied site."
