I need to know if they're a boy or a girl.

Question

I have 3 mice. brought them home March 28th 2008 from a birthday party.

They were just babies then.

I need to know how to find out if they're males or females.

I've asked my science teacher How to tell and she said when their old enough u will notice.

and i still can't see anything.

Answer 1

you will see but if you want to no now then look and if there is a biggish gape then it a boy but if you cant really see a gape then its a girl. also you can look for teats but depending on how old they are you may need to move the hair to see the skin

Answer 2

Your science teacher is right - you will notice when they're older enough - by all the babies!!

Mice can be pretty difficult to s*x if you're a beginner and especially just by the genitals. If your mice are relaxed however, you may be able to see testicles if they're males. Another easier thing to look for it teats - look at your mice tummies to see if you can spot teats - mice with teats will be females. If you are at all unsure, and seeing as this is your first time anyway, I would recommend you make an appointment with a vet who should be able to s*x them for you. You should organize this for as soon as possible though, as mice can start breeding from as young as 4-6 weeks of age  - meaning if you do have a mix of sexes you need to get them separated as soon as possible to prevent unwanted pregnancies.

Answer 3

males will have balls or lose skin near their bum females will have what looks like two holes.

Answer 4

You'll notice as the males will have...well 'male bits'  ;o)
