Help
So me and my partner found an almost newborn mouse outside on the 3rd of July.
So, before we did anything drastic, we tried to lure the mom back to the baby with baby mice sounds and food.
She never came.
So now, we waited and gave it pedialite (since we didn’t know how long since it had eaten) and now giving it kitten formula and even help it use the bathroom.
Can anyone tell us how old he is? And any other advice you might have?
Attached is photos and f Jerry (we found out it was a boy and decided why not)
