We thaw our rats overnight in the fridge. Then, we warm them up in water and blast them with the hairdryer.
Bit of a rush tonight so I ran them under hot water after they had thawed in the fridge over night - I was able to have my hands in the water stream but there was a bit of steam.
A patch of belly fur came off the weaned rat pup....does that mean it cooked? I don't see how it could cook if it wasn't hot enough to burn me. It still seemed raw.
