I don't post very much on forums but wanted to share my quick fix when I converted to F/T... I feed at night, and I feed at the same time each time I feed. Since I feed in the evening, I will let the food thaw out at room temperature. Some may not agree with this and that's OK, I just want to share what worked for me... So here are the steps. I take a bowl big enough to submerge the entire rat/prey in and fill it half way with water then take a grocery store bag (don't use paper hee-hee) cut it so that it's big enough to cover the bowl and line it like a pie crust... Now imagine you're looking at a swimming pool with a plastic cover over it, you jump in and make an indent of your body in the plastic. OK, now do this in the hot water bowl with the food item. I find the plastic bag keeps from cooking the insides of the prey. OK this may be the part some don't agree with. I microwave the water (about 1 minute) before placing the bag over it so that it will shorten the time I need to leave the food there to warm up. Since we're talking about balls, the food should heat up in about a minute or so. I found this seems to heat the food pretty evenly. It's very time consuming and may get old, but I was determined not to feed live to my kids... You might want to try this and see if it works. Hope this was helpful.
Blessings,
