How do Guinea pigs have sex?
Well, obviously, if you put any two animals, a male and a female, together, they will most likely end up having babies. Yes, it is the same for guinea pigs. Every, about 14 to 18 days, the female goes through her cycle. This is when the mating can take place. The female will lie down on her stomach, with her rear slightly up. After the mating has taken place, you can expect the pregnancy to last about 3 months. To figure out what sex a guinea pig is, all you have to do is gently push on the stomach down near the guinea pig’s private parts. You can do this with just two fingers, usually with your index (pointer) and the middle finger, and do this very gently. If the guinea pig is a male, a penis will emerge in the private area.
