If you're raising an orphan mouse, you'll need to feed the mouse diluted kitten formula every hour or two until his eyes are open at around 2 1/2 weeks. Whether mom-fed or hand-raised, baby mice will be ready to nibble on a few solid foods from the time their eyes open until they are completely weaned at 4 weeks old.
