I ran a bath for my tortoise, and I always put warm water in a litter pan and put it in a bath tub full of hot water to stay warm...I put him in to soak after I got home from work, then my fiancé went in and used the bathroom, turning the light off...an hour and a half later I gasped and realized I'd left my tortoise in soaking! I quickly went and got him, all the hot water had drained out of the tub and he was in cold(room temperature, I guess?) water. I thought he was dead, but when I grabbed him he woke up. He's currently just basking in his warm spot. Will he be okay? It's technically time for me to turn the lights off, but should I leave it on a while?
