What I meant was that if you warmed them to offer to snakes, or even if they were at room temperature, they should NOT be refrozen. Actually, I'm mostly
opposed to all refreezing, but I understand the spot you're in...and they "remained very cold" so it's not as big of a risk.
gotcha gotcha. if it was only a few believe me i wouldnt be refreezing at all but its like 35-40 mice
