switching to f/t

[frankadank]

okay well my local pet store was out of the common live mice i would get for my ball python. they don't get more till tuesday and i don't want her to go hungry so i purchased 2 small frozen rats. i guess this can be a good thing cuz i'll see if she'll switch over. if she does i assume i should stick to f/t rats than? i knew at some point i'd have too cuz i can't get live rats around here. i only fed her twice so far and they were small mice. she took both perfectly and has a good feeding response. my problem is i hope she will take a frozen rat cuz she was use to live mice. what's some of the best ways to thaw them out? i prob will do overnight refrigerator after this but since today's feeding day and they ran out, im going to try hot water. now if she takes it i probably will switch her over to f/t rats, what's some good sites to order from? any other tips for f/t feeding? thanks guys!
