Civet is an animal whose anal secretions are used in perfumes. Why would anyone do that, you ask? Well, the initially pungent and repulsive smell, when used in small amounts, has a warm floral character when used in smaller amounts. If you don’t believe that something like this can smell nice, you should know that Chanel, Dior, Yves Saint Laurent, Givenchy have all used this note in popular perfumes like Coco, Chanel No.5, Diorissimo, Kouros, Gentleman, and more.
