Rabbit Gestation Calculator
Enter the breeding date to estimate when a rabbit doe is due to kindle. The default uses an average gestation of about 31 days and shows the commonly reported range. Treat this as a planning estimate, not a guarantee.

Frequently asked questions
How long are rabbits pregnant?
Around 31 days on average, though kindling commonly happens anywhere from about 28 to 35 days after breeding.
Why is rabbit gestation so much shorter than other pets?
Different species have evolved very different reproductive strategies. Rabbits have an unusually short gestation compared to many other mammals, which is part of why they can reproduce quickly under favorable conditions.
When should I prepare a nest box?
Many breeders prepare a nest box around day 28 to be ready before the doe kindles, since exact timing within the normal range cannot be predicted precisely.
What if the doe was with a buck for more than one day?
Then the exact breeding date is uncertain. Use the earliest and latest possible dates to estimate a range of possible kindling dates.
How is this different from the Guinea Pig Pregnancy Calculator?
It uses a rabbit's much shorter gestation length (about 31 days) instead of a guinea pig's (about 59 to 72 days), which are very different reproductive timelines despite both being small pets.
When should I contact a veterinarian?
If you have any concerns about the pregnancy, if kindling does not occur within a reasonable window past the estimate, or if the doe shows signs of distress, contact a veterinarian experienced with rabbits promptly.
