Signs of guinea pig pregnancy include weight gain, enlarged abdomen, increased appetite, and behavioral changes. A vet can confirm pregnancy through palpation or ultrasound around 2-3 weeks after breeding.
Guinea pigs typically have 1-6 pups per litter, with 2-4 being most common. First-time mothers usually have smaller litters, while experienced sows may have larger ones.
Your guinea pig will likely give birth between 59-72 days after breeding, with most deliveries occurring around day 65. Use our calculator to get specific estimated dates for your pet.
