Hibernation management is the most welfare-critical challenge in keeping temperate tortoise species, with incorrect practice causing death from dehydration, hypothermia or premature arousal.
Tortoise hibernation represents the single highest welfare risk in tortoise keeping and the most common cause of preventable death. Owners who allow underweight tortoises to hibernate condemn them to death from energy depletion. Those who hibernate animals in uncontrolled conditions expose them to temperature extremes that either wake them prematurely or freeze them. The welfare solution is systematic: weigh and measure the Jackson Ratio in September, bath regularly in October, check daily during the transition, and maintain temperature monitoring throughout hibernation. The British Chelonian Group and Tortoise Trust provide authoritative guidance that transforms outcomes for well-managed animals.
