Cheetahs are obsessed . . . with Obsession? According to a recent study at the Bronx Zoo, big cats can't get enough of this Calvin Klein fragrance. Zookeepers tested 24 fragrances and found this most universally appealing, and it is now even used in the wild to track jaguars by attracting them towards a recording device with the sweeter smelling — and more ethical — alternative to the carcasses that poachers use.Relying on mostly donations and duty free steals to fuel the captive felines' habits, the concept made me think of our own domestic animals at home. My pooch likes to sniff my legs after I've put on a particular coconut lotion, but doesn't show any interest in my perfume (except to run away from anything spritzing). Do your furry friends have a nose for non-edible fragrances?
