* Guinea pigs can get pregnant very quickly: Female guinea pigs can become pregnant within a few hours of mating.
* You can't always see signs of pregnancy: Early pregnancy signs in guinea pigs are subtle and often go unnoticed.
* Gestation is short: Guinea pig pregnancies last around 63 days. A female could become pregnant, give birth, and you wouldn't realize she was ever pregnant.
How to tell if a guinea pig is pregnant:
* Take her to the vet: A veterinarian can perform a physical exam and possibly an ultrasound to confirm pregnancy.
* Look for signs of pregnancy: As pregnancy progresses, you might notice signs like weight gain, swollen nipples, and a larger abdomen. However, these signs are not always present.
Important Note:
If you don't want your female guinea pig to get pregnant, it's important to separate her from males. You can either house them in separate cages or use a divider to separate them within the same cage.
