We have a 3 year old spur thigh tortoise who lives outside. She hasn't hibernated in the 2 years that we've had her but recently has been showing signs of slowing down. She's 100mm (10cm) and weighs 138 grams. Recently she's buried herself under about 5cm of damp earth - when we move her to a sunny spot she returns a few hours later to the damp ground. We're worried that she'll rot under ground. Should we keep her awake and feeding? Any suggestions? Thank you.
