Guinea pig pregnancy can sometimes be a surprise, especially when pet owners believe their guinea pigs are both male. The phrase "You were told they were boys..." reflects a common mix-up among guinea pig owners, as distinguishing the sex of young guinea pigs can be challenging. Typically, female guinea pigs, called sows, have a gestation period of around 59 to 72 days, during which their physical and behavioral changes become noticeable. Common signs include a growing abdomen, nesting behaviors, and increased appetite. It's essential to provide proper care for a pregnant guinea pig like Bambi, ensuring she has a nutritious diet rich in vitamin C, ample space to move, and minimal stress. Expecting females should also be monitored closely to avoid complications such as pregnancy toxemia, which can be life-threatening. Post-pregnancy, guinea pigs usually give birth to fully furred, active pups that can eat solid food almost immediately. Owners should keep the new family in a safe and clean environment, providing fresh hay, water, and guinea pig pellets to support the mother and her babies. Thor and Bambi’s story highlights the importance of understanding guinea pig biology and responsible pet ownership. For those new to guinea pigs, consulting a veterinarian skilled in small animals is recommended to confirm genders and provide guidance on breeding and care.
