Maybe what he ment was that once the mice are thawed out (ie-room temp) it would illicit more of a feeding response if the mice were heated to temp of a live mouse (much higher than room temp) These are pit animals, sensitive to heat fields. That may not be what he means at all, but why not give him the benefit of a doubt before pontificating about how he's 'mentally challenged'. If he didn't know that they needed to be thawed out, then.....wow....that is really stupid...ah well.....
