Research overview: vomeronasal receptor repertoires in cats

Vomeronasal sensory neurons express specialized receptor families, often termed V1R and V2R types, that detect pheromones and related chemical cues. This overview surveys what is known about these receptor repertoires in cats and how their size and diversity relate to the animal's chemical communication. The complement of vomeronasal receptors reflects the range of social and reproductive signals a species detects through this channel. The survey relates the molecular repertoire to behaviors such as flehmen and to the detection of scent marks. It situates the cat among other mammals studied for vomeronasal receptor diversity. Understanding these receptor families grounds pheromone perception in genetics, explaining how the vomeronasal organ recognizes specific chemical signals. While many details remain to be worked out, the topic connects the molecular biology of chemosensation to the rich pheromonal communication that organizes feline social and reproductive behavior.
