The jury's still out on whether cologne will attract a romantic partner, but this one will lure a jaguar out of the brush so you can take pictures of it.

Biologists studying the big cats in Guatemalan rain forests had trouble photographing the stealthy predators, until they turned to Calvin Klein's "Obsession for Men."

Since jaguars are able to smell it a half mile away, the investment pays off. The cats come running and stick around, rubbing up against the rocks and wildlife cameras spritzed with the scent long enough for researchers to get detailed photos of the cats.

The WCS discovered the animals' obsession with Obsession during an experiment at the Society's Bronx Zoo in New York. Pat Thomas, the zoo's general curator, tested 24 fragrances on big cats to see which ones would keep their curiosity the longest.
