I live in Cyprus and was given 2 Mediterranean tortoise when they left the island one is 8 yrs old the other is 6 male & female. They went into hibernation the beginning of December. I have put them in a box in a cupboard under the stairs. My problem is this our temperatures in Cyprus are very warm in the day now its 20 degrees but at night it goes down to about 11 degrees...........how long will they hibernate for? are they ok in a box filled with hay under the stairs? will they wake on there own. I have looked on the web too much conflicting advice as i dont live in a cold country. Any advice for now and future would be gratefully received as i know very little.
