I feed frozen rodents to all of my snakes (except for one-a baby sand boa who will only take live pinkies) and I find it to be the best way to go in my opinion. Frozen is better because it is cheaper, safer and much more convenient.

I thaw my rodents by placing them in a spare rubbermaid container and then letting them sit in hot (not scalding hot, but very warm) water for about 1/2 an hour.....if the water gets cold or the rodent isn't thawed all the way, I refill the tub with new water.
