How do you know if your guinea pigs a girl?

Answer 1

To tell if your guinea pig's a girl, you should turn over the guinea pig and look underneath you'll see a "Y" and it will look like it is Clearly a "Y" with a little dot at the top, but very tiny and in between the two lines of the "Y" at the top.

If your guinea pig is a Male, you will see that the "Y" looks more like the letter "i" and if you press over the dot on top of what you think is the letter "i" you will see something pop. But you can only usually tell the guinea pig's gender after 2-3 weeks of age.
