I suggested the rat pup (cats have kittens, cows have calves, and rats have PUPS) weighed in appropriately because OP has tried mice and a rat pup with its eyes closed will not eat the snake making it safe to leave in there for two days. I would not leave any rodent with its eyes open in with a refusing reptile for more than a couple hours, weaned or not. Eyes open = teeth=ready to eat a live snake if need be to stay alive. No need to bash me, I have raised hundreds of hatchlings and never ever have had to feed mice. Not one single time. I do not like mice and I have never had a hatchling not thrive just fine on rats from the get go. Certainly worth a try! Done.
