How do the snow leopards know where their friends have been before?

Snow leopards use their keen sense of smell to gather information about their surroundings and track the movements of other leopards. They leave scent markings, including urine and scratch marks on trees or rocks, which convey information about their identity and territory. By detecting these scents, they can identify where other leopards have been and understand their social dynamics. Additionally, their acute hearing and vision help them be aware of other animals in their vicinity.
