Thawed in car

So it's been 90+ degrees here, we bought some mice last week frozen from petsmart, but had to do some grocery shopping, our car AC broke so by the time we got home all the mice had thawed, they were still cold, just not... frozen.

I should probably just call it quits and buy new ones right? They were out there for a few hours probably.

The fact they were still cool is a positive. Usually 1 thaw and refreeze is fine. I'd personally toss them in the freezer and let my nose be my guide. If they smell fine, like typical f/t rodent anyway, then I'd go ahead and feed without worry.
