Research overview: contraception for population control in captive felids

Managing the size and genetics of captive felid populations sometimes requires preventing reproduction in animals that are genetically overrepresented or surplus to program needs. This overview surveys contraceptive methods used in zoo cats, including hormonal implants and other agents, and the goals of controlling population growth while preserving the option to breed later. It reviews concerns about the reversibility and health effects of long-term contraception, such as uterine pathology associated with certain progestins, and the search for safer alternatives. The review connects contraception to studbook management and welfare. Understanding contraception in captive felids clarifies how programs balance the need to limit reproduction against the importance of maintaining future breeding capacity and animal health.
