The reason cats respond to catnip is because catnip actually smells like the urine of a dominant female cat. After cats eat, they always immediately bathe themselves. A seabird called the fulmar is capable of spitting a foul-smelling, yellowish oil at intruders to their nests.
Fulmars even smell like their oil.
Fulmar egg shells that have been in a museum for 100 years still smell. A dog s sense of smell is one of the keenest in nature. If a pot of stew was cooking on a stove, a human would smell the stew, while the dog could smell the beef, carrots, peas, potatoes, spices, and all the other individual ingredients in the stew. The zorilla is the smelliest animal on the planet. The children's famous rhyme,'Ring around the Rosie' was actually a small story on fact.
