How do you know if your guinea pig is pregnant?

Determining if a guinea pig is pregnant can be challenging, but there are several signs you can look out for:

Signs of Pregnancy in Guinea Pigs

1. Increased Appetite: Pregnant guinea pigs often eat more than usual to support their growing fetuses24.
2. Weight Gain: As the pregnancy progresses, guinea pigs will gain weight, particularly noticeable around the third week15.
3. Enlarged Abdomen: The abdomen becomes visibly enlarged as the fetuses grow45.
4. Behavioral Changes: Pregnant guinea pigs may exhibit nesting behavior, become more lethargic, or show changes in social interaction34.
5. Swollen Mammary Glands: This is a physical sign that can indicate pregnancy3.
6. Vaginal Discharge: Some guinea pigs may experience vaginal discharge during pregnancy3.
7. Feeling Fetuses: After about two to three weeks, you might be able to gently feel the fetuses by running your hands lightly along the guinea pig's sides1.

What to Do If You Suspect Pregnancy

If you suspect your guinea pig is pregnant, it's crucial to consult a veterinarian. They can confirm the pregnancy and provide advice on proper care during and after the pregnancy14.

Gestation Period

Guinea pigs are typically pregnant for 59 to 72 days, averaging about 68 days35.
