Pocket just had a surgery and I have not put substrate back in his rubbermaid container. I just have some damp paper towels in there now. I just have a regular heating pad under the container. It's not working well with the paper towels. I feel like he's sitting on cold, damp towels. Not good. What else can I do? His temp was at 80° & it's dropped the last 12 hours. What else can I do?? I do have a small zoo med under tank heater but I lost the little nubs they give you so air csn travel below. Please help!!!!
