The weather here in TX is insane. The freezing temps are causing power outages and I'm worried about my two girls.
I have two gliders and I'm unsure what to do to keep them warm if we lose power. Our house is VERY poorly insulated, some may even say drafty, and thus the cold is already an issue, so right now I have a space heater constantly on in my room but if we lose power that means no heater, heating pads, heat rock, or heat lamp.

Does anyone have any tips on what to do should the power go out and I need to keep my girlies warm during it?

If the power goes out during the day, you could always carry the gliders around in a bonding pouch - your body heat would help them a lot. Not sure about night time, though.
You can also put extra squares of fleece in their sleeping pouch and around their cage for them to snuggle under.
