Interesting topic for whenever the power goes out.. only thing I could think of is to take him into natural sunlight if warm enough but it's not that time of year obviously so yeah.. a little different for me I guess being in the desert & all..
My power JUST came back on here at the Jersey shore. I lost a tree frog to the cold But I kept my Beardie with me inside my sweatshirt against my chest... filled bottles with warm water and put him next to them wrapped in a towel at night... it got us by for a week, finally got him into a petstore (don't be afraid to call the big chain places either!) that had power a day ago! if possible call around people everywhere are doing their best to help...my animals are all spread out among friends, family & a shop that will forever have my business!
