The three primary ways cats mark their scent are through urine, facial rubbing and gland secretions. Urine marking is the most common form of scent marking, and cats will often spray urine on objects and surfaces to mark their territory. Facial rubbing is another way cats mark their scent, and cats will rub their face against objects to leave their scent behind. Gland secretions are also used by cats to mark their scent. Cats have scent glands located on their cheeks, chin, forehead, and tail, and they will rub these glands on objects to mark them with their scent.
