My grandmother is just terrified of mice. I would tell her, eventually, that I was keeping the mouse. She knows that I get attached easy. I have seen him nibbling but not actually eating. The wetness was probably from the water dish I put in there. There is no water dish in there now and I have been attempting to give him water by a dropper.

Would it be ok to feed him on cows milk or even KMR? (Kitten Milk Replacement)

I'll punch more holes in the top to better circulate the air.

He stops shaking when I pick him up. He might just be cold. It is cooler in the bathroom (where i keep him away from the cats. If he were in a cage, I wouldn't have to worry, but a tupperware container is oh so easy for them to get into.)
