baby mouse 911! help!

picked up a newborn mouse from a breeder... dont know why he bought one so young as it is WAYYY too small to feed any of his babies. anyway, decided if i could save its life, he would be a pet. He was taken from his momma last night. i have been feeding him kitten milk from a syringe and he is in a cozy little nest in a seperate feeding tank with a light.. temp is 80 degrees so i just pulled the light off. Any pointers or tips on how to keep this little guy pushin. He seems to be a little more lively now that he has food in his tummy but he did go almost 24 hours with no food.

:(

we raised a few rats from very early, my wife mixed milk with some crushed up crispix (yes the cereal) and warmed it up a bit. then she put it in a syringe and held the rat and fed them like that. sometimes they would only drink eat out of her hand. they would go crazy for it, they loved it. although she did have to wake up a couple times a night to do this. kinda like having a kid. but all 3 are alive and healthy pets today.

I would send him on a ride down the toilet express. Mice are waaaaaay more trouble than rats.
