How Long Is A Guinea Pig Pregnant

Guinea pigs have a relatively long gestation period for their size averaging 59–72 days. It is not uncommon for first-time mothers to give birth a few days outside of this range. You’ll know your guinea pig is getting close to giving birth when she starts to build a nest out of straw and any other materials she can find. The nest is used both for labor and delivery and for raising the newborns.

Your guinea pig will give birth to anywhere from one to six babies though the average litter size is three. The newborns are called “kits” and are born fully furred and with their eyes open. They are able to eat solid food immediately but will continue to nurse from their mother for the first few weeks of life.

Once the kits are born it’s important to keep a close eye on them to make sure they are nursing and staying warm. If you notice any of the babies are not nursing or seem cold you will need to bottle feed them and provide supplemental heat. Guinea pigs are very vulnerable to drafts so make sure their cage is in a warm protected area.

As the kits grow they will start to explore their cage and play with each other. Around four weeks of age they will be fully weaned and ready to be moved to their own cage. At this point you can also start to introduce them to other guinea pigs if you have multiple pigs in your home.

If you have any questions or concerns about your guinea pig’s pregnancy or the birth process be sure to talk to your veterinarian. They will be able to answer any questions and help you ensure a healthy pregnancy and delivery for your guinea pig.
