Long story that I don't want to explain. I'm stuck with a very cute rat pup. He has fur and looks very close to opening his eyes. I have Goat's Milk feeding formula and he has been drinking it. I read that you have to stimulate them to go potty, but this will be his second feeding and he won't go. I have him in a shoebox with a t-shirt and a heating pad.

I need some help from anyone. Anything would help. Thanks! He's just too cute to watch him die
