It is advisable to carry out in the same terrariums in which animals are kept, the same groups (or at least in pairs).
Duration of hibernation is from November till February and divided into:

  • Preparatory period - two weeks with gradual reduction in temperature to 18°C and decreasing a light day to completely turn off lighting.
  • Hibernation period. The temperature is 18°C. Hiding places are obligatory. Fresh water is available all the time. Do not feed lizards.
  • Completive period - two weeks with gradual increase of temperature to 26-28°C and increasing a light day to 10-12 hours.

Then normal feeding and maintenance follows. Hibernation is a stimulus to the reproduction (June- September).
