Research overview: cooperative defense of kills against scavengers

An overview of how social and grouping behavior in cats functions partly to defend kills against kleptoparasites and scavengers. In lions, larger groups retain carcasses against mobbing spotted hyenas more successfully than individuals, so the threat of losing food can favor sociality and influence optimal group size, while even normally solitary cats may tolerate kin at kills. This survey synthesizes evidence on how kill defense shapes group living, the role of male lions in deterring hyenas, and how the balance of competitor numbers determines who keeps the carcass. It connects food competition to the evolution of social behavior in felids and to the broader theme of kleptoparasitism. The topic shows that defending kills, not just acquiring them, is a key selective force on cat behavior.
