Cats use their sense of smell to communicate with other cats and humans. Cats have scent glands located on their cheeks, forehead, and paws, which they use to mark their territory and communicate with other cats. Cats also have a Jacobson's organ located in the roof of their mouth, which helps them to detect pheromones and other scents. Cats generally enjoy the scent of catnip and other herbs, as well as the scent of their owners. Cats may also enjoy the scent of citrus fruits, such as oranges and lemons. Cats generally dislike the scent of strong perfumes or cleaning products.
