Very difficult - would you have to wait until it is cold enough for him to hibernate?Rather cold......brrrrrrr - am shivering only at the thought. Am planning to go to AQABA (the warmest city here), but OLI is worrying me and stopping me from moving: he does NOT eat unless I hand feed him. Spoiled brat!Adam suggested hibernating him.
I don't know much about it except that I've read they have to be healthy enough/right weight hydrated etc but not have too much in stomachs to survive it.
Could you do a vet visit with him to check that?
