Re: room temps (conflicting advice)
No, that's not okay. Hedgehogs need to be kept at at least 73 degrees Farenheit at all times, which would be about 23 degrees Celsius. You need to get a space heater or a ceramic heat emitter in order to keep their cage at the right temperature. I'm guessing they haven't tried to go into hibernation before, but you really should keep the heat up. They'll be more comfortable, and you won't be running dangerous, unnecessary risks.
