About the Cat Pregnancy Due Date Calculator
Cat pregnancies (also called gestation) typically last between 58 and 67 days, with an average of about 64 days from the day of mating. Unlike dogs, cats don't have a single fixed gestation length, which is why tracking the mating date closely and estimating a due date range is so useful for breeders and owners alike.
Knowing your cat's estimated due date helps you prepare a quiet, comfortable nesting area, schedule a pre-birth vet check, and recognize when labor may be approaching versus when it's simply too early to worry.
Frequently Asked Questions
How long are cats pregnant?
Most cat pregnancies last 63 to 65 days, though anywhere from 58 to 67 days is considered normal.
How accurate is this due date?
This calculator gives an estimate based on average gestation length. Actual delivery can vary by several days, so treat the result as a window to prepare for rather than an exact date.
What are signs that labor is close?
Nesting behavior, restlessness, decreased appetite, and a drop in body temperature are common signs in the final 24-48 hours. If you notice these signs well outside the estimated window, or if your cat shows signs of distress, contact your veterinarian.
