I have been converting a shop building into my new chameleon room, and the panther chameleons are now officially living in it. Hopefully, by the end of my weekend, the leaf chameleons will be too. A power outage could easily wipe out my collection, because the temperatures get very low here. The shop is equipped with (new) electric heaters, and also has a wood stove. The wood stove is my backup in case of power outage. It can pretty easily heat the 800 sq ft shop up to about 70+ degrees.
I also found an alarm system online that I installed. It is programmed to call 3 phone numbers if the temperature drops below 55 degrees or goes above 85.
