Cat Gestation / Due Date Calculator
Calculate the queening due date for a cat (queen) from the breeding date (gestation ~65 days), with pre-queening management reminders.
A queen's gestation is about 65 days (9 weeks); farm cats are valued for rodent control around grain stores. Enter the breeding date to get the due date plus key pre-queening management reminders.
Indicative planning figures based on published research averages. Local soil tests, varieties and weather change actual requirements — confirm with your agronomist or extension officer.
Livestock keepers and vets use the free Cat Gestation Calculator to mark the queening date and schedule dry-off, vaccination and pen moves in advance.

Frequently asked questions
How long is the gestation period of a cat?+
About 65 days on average (± 3 days is normal). A queen's gestation is about 65 days (9 weeks); farm cats are valued for rodent control around grain stores.
How do I calculate the queening date?+
Add the gestation length (~65 days) to the breeding date. This tool does it instantly and also marks a normal range, since births a few days either side of average are common.
What should I do before queening?+
Prepare a clean, quiet birthing area, ensure pre-birth vaccination and (for dairy animals) timely dry-off. The tool lists these dates counted back from the due date so you can schedule them.
