How do you take care of baby mice?

my cat likes to hunt mice and anything he can get his paws on. he brought one up and it was fine and then he brought another one up and they dont have any cuts so theyr fine. their eyes are open and they can walk. they are currently in towels and clothes and cuddling. i looked up a little on how to care for them and it said to feed them condensed milk with an eye dropper and let them snuggle. i dont know if theyll be able to live without a mother and i cant release them back because i had to save one from my cat who was about to hurt it and i had no choice to pick it up with my bare hands. so they both have plenty of the smell of human on them. but any advice even on how to feed them or take care of them would be very helpful. i need allll the info i can get thanks so much for any help :) *squeak* :p
