Keeping captive tortoises healthy and well is a significant challenge. Because they are ectotherms, these reptiles are totally dependent upon external sources to maintain body temperature and therefore metabolic function. Their physical environment is vital for them to remain healthy, and as owners, we have to provide sufficient choice in the environment for them to be able to experience as near optimum conditions as we can. Covering all aspects of tortoise husbandry and welfare, this book advises on: - Suitable temperature ranges, light sources, humidity, substrate, space, and seasonal changes according to individual tortoise species; - Specific dietary requirements, and opportunities for expression of natural behaviours including reproduction. - Variety of environments, ranging across indoor and outdoor accommodation options, to achieve optimum conditions for tortoises in captivity Written by a leading clinical animal behaviourist, this book is an important read for anyone involved in tortoise welfare, from students and zoo rescue staff, to pet owners and the veterinarians advising them.
