What is the gestation period for guinea pigs?

The gestation period for guinea pigs typically ranges from 59 to 72 days. This relatively longer duration compared to some other small mammals reflects the developmental needs of guinea pig young, which are born precocial. This means they are more developed at birth, able to see, hear, and move around shortly after being born. This extended gestation period allows for the proper growth and development of the fetus, ensuring that the offspring are more self-sufficient at birth. Understanding this aspect of guinea pig biology is crucial for anyone involved in their care or breeding, as it directly impacts their breeding practices and the care required in the final weeks of pregnancy.
