King cobras in zoos require specialised husbandry for their specific thermal, spatial, and behavioural needs as the world's longest venomous snake.
King cobra welfare in captivity depends critically on appropriate thermal environments, adequate space for a large active snake, and appropriate prey variety. Inadequate temperature gradients prevent normal thermoregulation, impairing digestion, immunity, and behaviour. Insufficient space for an animal that naturally patrols kilometres causes chronic inactivity and associated health problems. Stress from improper handling, noise, or social proximity to other cobras suppresses immune function and increases disease susceptibility. While reptile welfare has historically received less attention than mammalian welfare, there is increasing recognition that reptiles have thermal preferences and aversion to noxious stimuli consistent with negative welfare states.
