SOME snakes will eat carrion in the wild- BPs are not known to do so. King snakes & indigo snakes are some that probably would.
For anyone else that "thinks in Fahrenheit", the temperatures referenced are roughly 40*-60* F -quite warm. If kept at 40*, that's like being in the refrigerator- not too bad, especially since they started as frozen. But 60*? The box obviously wasn't very insulated, so I'd say they're garbage, sorry. Here's the thing: (to quote myself https://ball-pythons.net/forums/show...=1#post2762743 )
Prey such as frozen rats need to stay frozen- otherwise there's a loss in quality- even if technically safe enough to feed, your snake can only eat one right now. When you re-freeze them, then try to thaw & feed them later, they turn to mush, may split apart when the snake grabs (bites or constricts) them, & may also be spoiled. Freezing doesn't kill the bacteria in the rodent's GI tract- it just keeps it from growing. All bets are off once they are thawed- that's why we don't re-freeze & re-offer rodents that a snake happens to reject.
In the future, you should make a habit of transporting frozen food in an ice chest- then a little forgetfulness won't cost you so much, at least not so quickly.
