How long is a guinea pig pregnant before it gives birth?

A guinea pig’s gestation period is generally 59 to 72 days, which is about two months. During pregnancy, the owner should provide a suitable living environment that is clean, quiet, and kept at an appropriate temperature.

Try to avoid frightening the pregnant guinea pig or causing large mood swings, as this can lead to miscarriage. During pregnancy, the owner should also provide plenty of nutrition, making sure the guinea pig gets enough calcium and vitamins.
