Snow leopards spend the majority of their lives alone, but they spray the rugged landscape along the way to send signals to other cats. Not only helpful in locating individuals (like relatives or potential mates during breeding season), their urine helps mark their own distinct territories.
Scent communication is important to many animals. In fact, the domestic cats we know and love answer to similar instincts. Spraying inside the home and around your property may occur, but another important feline behaviour is scent-marking.
