What does it mean if baby mice have a large flat white thing under their skin on one side of their belly?

Answer

If you are hand raising a baby mouse and you see a white spot on the left, middle side of its belly, this means it needs to excrete solid/liquid waste.(pee/poop)If it has no mother to help it, then you must assist. After each feeding, gently massage its abdomen to rectal area with a warm, damp cloth. This will help facilitate the process. If this is not done, your mouse will explode. (Just kidding.) It will, however, most likely develop diarrhea and most definately a horrid belly ache. If your mouse has a mother and the white spot does not dissipate upon excretion, try the aforementioned suggestion. If you are still unsuccessful, call a vet or a local wildlife center or animal rescue league.

Answer

Milk rings! Aww! The cutest thing ever. The "large flat white thing" is mother's milk! Since the skin is so transparent when they're still pinkies, then you can easily see the milk still in their tiny little tummies.

It's nothing to worry about. Just means you have healthy and well-fed little babies.
