How do I raise a pinky mouse? - pinky with bangbus

My nephew bought a pink mouse to feed your garden snake, but could not feed the snake. How can I do that? I was so fed as often as possible during the last 2 days with soy milk, regular milk and milk with a baby kitten Seringe very low. It is located in a small cage with a light on them.
