  2. The calculator estimates a due date 65 days from the first breeding, as cats have a typical gestation length of 63-67 days.

What information do you need to use a cat pregnancy calculator accurately?

  • The exact date your cat was first bred, if known. If the date is unknown, estimate when your cat first went into heat and could have mated.
  • Your cat’s breed, as some purebreds have slightly shorter or longer gestation periods.
  • Dates of any subsequent matings, as kittens don’t always arrive precisely 65 days after the first breeding.

Cat pregnancy calendars provide an estimated due date based on the first day your cat mated. This useful for estimating the due date so you know when to expect those tiny paws.
