Yeah, I thaw my feeders with lukewarm water and when they no longer have any cold spots and feel soft and malleable, I take it out, hold it by the tail and blast it with the hairdryer for a minute or two. I usually do this last bit beside my tank, and within seconds, Lazy is out looking for his food

I tried the heat lamp method once, but he ended up striking the mid-section and then eating the feeder but first Now I stick to blasting the head with the blow dryer XD

Hope you get yours eating!
