I'm thinking of getting a bearded dragon, however, I live in northern California and we are prone to power outages due to fires. During the day we are able to run a generator but during the night we are not. The lizard would have to go without heat for nine hours whenever we have a power shortage which usually can last for a couple of days up to a week. During this time, temperatures can drop to around fifty degrees Fahrenheit. Is this okay for a bearded dragon?
