Identifying genders..

Hey! Can anyone give me a few tips on identifying the gender of a mouse? I'm looking to get a male mouse pretty soon (instead of the trio I said I'd get) and I want to make sure it's actually a male. Thanks in advance!

There's a little vaginal opening behind the 'nub' on females. Needless to say, not present on the males.

The distance between genitalia and anus is also larger on boys and of course, they often (but not always) have very prominent testicles. Don't be fooled though. They can hide them! If you keep a male you will probably notice these bits within a week.

Thank you! This will be very helpful info! Smile

Also females have nipples, males do not. More here: https://www.petmousefanciers.com/t45-sexing-mice.
