Research overview: scent marking as reproductive advertisement in felids

Solitary cats rely heavily on chemical signals to advertise reproductive status and locate mates across large ranges. This overview surveys how felids use urine spraying, scrapes, cheek rubbing, and gland secretions to communicate estrus, territory occupancy, and individual identity. It reviews evidence that scent marks convey information about a female's reproductive condition and a male's presence and quality, enabling time-shifted communication between animals that rarely meet. The review considers seasonal and estrous changes in marking rates and the chemistry of feline pheromones. Because scent marking mediates mate finding in dispersed populations, understanding it illuminates felid mating systems and informs captive management, where olfactory cues can be used to stimulate reproductive behavior.
