Guinea Pigs have a long Gestation period compared to other Rodents, generally 71 days. Their young are born fully formed with hair and can be eating solids within 24 hours.

This chart helps you to count from the day of conception to the date of birth.

The left hand column in Green is the day of pairing and the Red column is estimated due date. This chart is extremely handy for any cavy owner.

Guinea Pigs can come into season about every 3 weeks.

Please breed responsibly.
