How can I tell if my mouse is a boy or girl?

I can't see it's you know, but it just might be because its too small or it doesnt have any
D=
because like I was hanging it by its tail
but like stopped, because it looked sad and scared and annoyed
so yeah.

usually the guys have visible nuts yo

ROFL!
Sorry.
That gave me a laugh.

Give it your phone number. If it doesnt call u, its a boy.

wait till its older, but.. one of my mice we thought he was a boy and then a gil and thn a boy and there were heaps of babies we still didnt figure it out lol, and then the he-she mouse died so I guess we'll never know.

sad. it was my favourite mouse too. its name was cous-cous

Males definietly have prominant nuts and females dont its pretty easy.

boys got the big hangers...

there should be be some balls right under his tail, just look. if nuthin there... its a girl.
