How can you tell if your female mouse is pregnant?

Q: Okay, so I have a few female mice and a few male mice. I am already pretty sure that Sandy (female mouse) is pregnant. But I need to know, HOW CAN I TELL?? And PLEASE DO NOT say, “Yes, they probably are pregnant,” BUT I’M NOT ASKING THAT! I need to know, HOW CAN I TELL?!

A: well i was breeding mice to feed to my lizard and snake and my mice would get pregnant all the time but only certain ones would get pregnant and if your mouse does get pregnant then you should look for things like a lot more eating growth in the stomach not length but width in the stomach sleeping more not interacting with the other mice much not even the father that much and they should be born within 2 to three weeks after she gets pregnant but it really varies so you need to have a separate cage at the ready so you can keep the baby mice alive or if you keep the mice in the same cage then you need to feed them twice a day because if they get hungry they will eat the babies. Now if you forget to move them back to the other cage don’t even bother because they wont remember each other and they will fight so yea that’s the basics if you get a pregnant mouse.
