A Cat’s Sense of Smell is incredibly important to cats. A Cat’s Sence of Smell is 14 times stronger than a human’s.
Cats rely heavily on their Sense of Smell as they use scents to communicate, and gather information. Cats use this information to communicate messages to other cats, and sometimes humans, although we may not understand what they mean.
Besides their noses, cats can smell with something called the “Jacobson’s organ” located in the upper surface of their mouths. This is what cats are using when they scrunch up their eyes and open their mouths after sniffing something intently.
