Is my mouse okay?

I m currently fostering a baby mouse. It s about a week and a half old. It has a full body of hair and looks as if it s going to open its eyes any day now. When I first got it about a day and a half ago it pooped basically on it s own with no stimulation, but it hasnt pooped since then. Its peeing every time I feed it after I run the belly area. I feed it kitten formula but diluted more to avoid dehydration. I dont know what to do at this point. Please help.

Oh for god's sake, either take it to a vet or kill it, they are vermin.
