- Weight gain: Pregnant guinea pigs typically gain weight, especially in the abdomen.
- Behavioral changes: Pregnant guinea pigs may become more irritable or aggressive, and they may spend more time resting or hiding.
- Changes in appetite: Pregnant guinea pigs may have increased appetite or pica (eating non-food items) while others may lose their appetite.
- Increased urination: Pregnant guinea pigs may urinate more frequently.
- Palpating the abdomen: Gently feeling the abdomen of a guinea pig may reveal the presence of fetuses, especially in the later stages of pregnancy. However, it's important to be careful and avoid causing any discomfort to the animal.
- Presence of a vaginal plug: After mating, a guinea pig may have a vaginal plug, which is a small, white discharge that seals the vagina. However, not all guinea pigs develop a vaginal plug.
It's important to note that not all of these signs are conclusive evidence of pregnancy, and some of them may also be associated with other health conditions. If you suspect your guinea pig is pregnant, it's best to consult with a veterinarian for confirmation and appropriate care.
