If males and females are housed together, and babies are not desired, the male should be neutered. If used for breeding, female guinea pigs, also known as sows, should be bred the first time, at less than 6 months of age. First time mothers over this age may be unable to give birth naturally as their pelvis may not open allowing the babies to pass through. Baby guinea pigs are precocial. This means they are born fully furred with their eyes and ears open and functional. Though they may nurse for up to three weeks, these little ones begin nibbling on regular foods almost immediately.
