Okay thank you for the quick response! I did weigh him, and he is losing a little bit of weight but not very much. Over the 7ish months it’s been about 200 grams (1660–>1445g). That makes sense that it is not a good idea to have the rats still be partially frozen and scare him from eating, but what I am wondering is there a way to be sure that the inside is not frozen at all?
