Tortoises in captivity are ectothermic reptiles that require precise thermal management and appropriate substrates to maintain physiological function and welfare.
Tortoise welfare in captivity is fundamentally about meeting the thermoregulatory and dietary needs of an ectotherm in environments that may be profoundly different from their natural habitat. Cold, inadequately lit tortoises do not simply become inactive — they become physiologically compromised, with impaired immune function, poor digestion, and increasing susceptibility to respiratory and metabolic disease. Providing appropriate thermal gradients, UVB lighting, varied diet, and suitable hibernation conditions addresses all major welfare domains for captive tortoises.
