Disastrous hibernation due to below freezing temps
George came to me in the summer so first time hibernation for me with him. He’s 52 years old so well used to hibernation in the UK. He’s never lived in doors apparently. Temps got to near freezing in my insulated garage so I had no other option but to bring him in the house after only 6 weeks of hibernating. He was double boxed with insulation but still it was too cold. Did the waking up process with him slowly over many hours, room temp, then Luke warm bath then he had the option to go under the lamp if he wished. He’s not fussed about the lamp at all! He has started eating yesterday after 5 days but as soon as he’s finished his food he’s straight back to burrowing! Before he started eating he just burrowed unless I put him under the lamp and only then did he stay under it for a few minutes. He’s getting 2 baths per day but I have to get him up for these too. Will he snap out of this and stay awake more of his own accord? Is there anything else I can be doing to help him?
And yes before anyone says I know a fridge would be best for hibernation but due to no funds for purchase of one and the astronomical price of electricity that is not an option for me I’m afraid so over wintering is my only option and my lamp is far more economical to run.
Thank in advance for any assistance.
