Animals mark their territory in various ways, including by using scent markings, visual markings, vocalizations, and physical boundaries. Scent markings can include urine, feces, or scent glands that animals use to communicate with other members of their species. Visual markings may involve scratching trees or other objects, while vocalizations can warn other animals to stay away. Physical boundaries, such as digging or building structures, can also help animals establish and defend their territory.
