She's eating F/T rat pups right now. I think I'll try the hairdryer thing next time and see what happens. I've been putting them under a lamp to warm them up but that'd probably be faster. So far she's never actually refused food, it's just taken her a long time to take it.
Oh and try to get the rat to a 100 degrees. Which is normal rat body temperature. My albino locks on really fast when the rat is at that temp but any cooler than that it takes a while
