Do NOT scent with lizard or frog. Before you do anything else you need to know what the temps are in your hot spot. Cool side shouldn't go below 65 but anything above that and below 80 is fine. It will never need to be over 84 and 80-82 is just fine. Put the bedding back it. Get a small paper bag, like the kind you get at fast food restaurants, put a live small pinky and the snake in the bag, double fold the bag so it's difficult for the snake to escape, put the bag with the snake and the pinky back in the tank and secure that. Leave the snake alone overnight. Chances are that doing this once or twice will get him back on feed. I've produced several hundred peublans and have used this method on them and thousands of other milks and kings.
