I’d just like to add. It wasn’t me who said “it is a matter of metabolic conditons. [Temperature, Fat, Nest Insulation, Food Type and Availability and Air Pressure/Temp* [ ie gut air pressure] as to whether they are conditioned to go into torpor or not.]” Must have been someone else.
In my opinion, hibernation is a complex thing and it’s likely that both going into hibernation and emerging from it are triggered by a combination of factors. i.e. I think it is too simplistic to say that it is triggered by temperature/weather conditions or food availability, etc. Sadly, we don’t really know enough about it yet (and it may be one of those secrets which hogs never completely reveal!), although various people may have various theories.
