I just had two sucessful feedings of F/T (he was previously eating live and P/K). Here is how I thawed the meal......First, I took out the rat and let it sit out, in a plastic baggie, for 2 hours. Then, I let it soak in hot water for 15 minutes (to get it nice and warm). Finally, I dried it off with paper towel and set it under a heat lamp for a minute or two, concentrating on the head and belly area. Then, I did the "little rat jig" in front of his hide and he took it no problem. Good luck!
