Gestation Related Information:
This gestation calculator is provided to allow for easy calculation of delivery dates for your females after conception. If you suspect a mating, such as the presence of a stopper, finding pulled fur in the cage, or finding a fur ring on your male chin, note down the date, and input this into the day, month and year fields to the left. The expected delivery date will be displayed below the data entry fields, and is calculated as 111 days after the conception date entered. If you select the conception date of an existing pregnant female, the length of gestation in weeks is calculated, and advice on that stage of the pregnancy will appear here.
