I thaw in hot water for about 20 min and then lay the feeders on a paper towel under a heat lamp (about 6 inches away from them). About 10 min on each side and then as a last blast before I give them to the snakes. I cover the feeder, who is about to get fed, completely with the lamp (lamp on floor over the feeder) and heat for 10 sec on each side then 10 more sec on just the head. I only have 3 snakes now (waiting on the 4th) but if norm takes me around 45 min to feed.
