I have tried feeding my blood frozen thawed rat and she will not take it. She flicks at it but that's it. She'll take live like there's no tomorrow. The guy I got her from said he fed f/t. I'm not used to feeding frozen thawed but this is how I've been doing it (I do the same procedure with the corn and she takes it with no prob). I let it un-thaw at room temp. or if I'm in a hurry I'll put it in warm water to thaw faster. Then I take a hair dryer to heat it up. Last time I thawed her rat water got into the ziplock bag could that be an issue? I'm wondering if I bought too large of a rat but it is no larger than her body. I hate to keep buying frozen rats, especially if she wont take them. Around here they cost as much as live. If I can figure out why she wont take frozen I'd like to go through rodent pro and save a ton of $$$$. I bought the frozen rat at petco as well if that matters.
