Young field mouse

[Anjanette]

Hello, We found a young field mouse that our playful tabby cat brought to us. He doesn't seem to have any injuries except a very small puncture on his back that blead for less than an hour and seems to be better now. He is shakey or wobbley when he tries to walk, that's why we think it's a baby or maybe very young. It has hair and it's body is healthy looking. It's body seems small for the size of his head. We do see little tiny teeth but we aren't sure how to feed it. We've tried an apple slice, crushed kitten food in warm water (but doesn't seem to like it), clover from the front yard, and a tiny piece of bananna. Any input would be very much apppreciated.
