Hibernation is a biological process which occurs within reptiles and mammals where they 'sleep' through the cold weather.

It is important to consider which tortoises have the capacity to hibernate in their natural habitat rather than insist that all species always have to be hibernated in captivity. Not all tortoises hibernate naturally, if you are unsure of the species seek professional advice or prevent hibernation from occurring by providing your tortoise with suitable indoor accommodation during the winter months.

These step by step guides are designed for most Mediterranean tortoises which include Spur thighed, Hermanns and Horsefieldis, as sold by The Tortoise Lady. Most tropical species such as the Sulcata and Leopard Tortoise do not hibernate. Adequate indoor accommodation is essential when keeping such species which should be taken into account when homing such a large species all year round.

I have been asked on a number of occasions whether it is entirely safe to hibernate tortoises. Of course I can not guarantee a long and healthy life for every tortoise as sadly sometimes nature just takes over. I have, over the past 20 years, hibernated my own tortoises with equal success each year. If however you follow these guidelines, which are used by many tortoise enthusiasts, then you will be offering your tortoise a pattern of life similar to its natural habitat, where hibernation would naturally occur.

One important factor which you need to pay close attention to is whether or not your tortoise can or cannot be hibernated. In the wild some species hibernate as a natural cause. Others on the other hand remain active throughout the winter months. Essential conditions for a safe hibernation are summarised:

• The temperature should remain above 2 degrees C and below 10 degrees C

• Never hibernate a tortoise whilst its stomach contains undigested food.

• Always provide a fasting period before hibernation is to occur.

• No sick or underweight tortoise should ever by hibernated.

Follow these guidelines for approximate length of hibernation.

• 0-4 years - 4-6 weeks (see Juvenile Hibernation section).

• 4-8 years - 6-10 weeks

• 8-Adulthood - 10-16 weeks
