I just had a power outage last night - what a nightmare - I was sooooo worried about my babies. I had some of those heat packs from Reptile Basics but wasn't impressed with how warm they got - it was the first time I used them.

Maybe I did something wrong but the instructions said to open them/shake them and insert into the cage. I put one in each hide under the kraft paper that I use for bedding but it didn't seem to get very warm when I kept checking things.
