The event took place at a pet boarding facility in the UK, where a male guinea pig escaped from his separate enclosure and entered a large pen housing over 100 females. Staff discovered the incident after noticing unusual activity and later confirmed that nearly all the females showed signs of pregnancy. The male guinea pig, later dubbed “Randy,” was placed in temporary isolation following the incident.
Guinea pigs are known for their rapid reproduction cycle. A female can become pregnant shortly after giving birth, with a gestation period averaging 59 to 72 days. Litter sizes typically range from two to four pups, which explains the estimate of approximately 400 offspring resulting from this single escape. While such breeding rates are biologically plausible, large-scale accidental impregnation cases like this are rare in controlled environments.
The unexpected population surge posed logistical challenges for the facility, including finding new enclosures, arranging veterinary care, and preparing for adoption coordination. Staff expressed concern about the resource strain, while animal welfare organizations offered support in managing the upcoming births and rehoming efforts.
The incident highlights the importance of strict enclosure management in pet care facilities, especially with species known for high fertility. 🐹🔒
