Research overview: maternal separation, hand-rearing and development in big-cat cubs

Early-life experience profoundly shapes felid behaviour, and the routine hand-rearing and early maternal separation used in cub-petting and some breeding programs carry developmental risks. This overview surveys research on the effects of maternal deprivation and hand-rearing in cats, including impaired social development, abnormal behaviour, difficulties integrating with conspecifics later, and welfare costs of intensive human handling during the sensitive period. It contrasts these with cases where hand-rearing is genuinely necessary for survival and how best to mitigate harm. It also considers how early experience influences adult temperament, breeding success and stress resilience. The synthesis frames maternal care and appropriate early socialisation as foundational welfare considerations, with implications for both commercial handling and managed breeding.
