Pregnancy calculator for Cats

Answers the question: When is the birth date for my pregnant cat?

Pregnancy in cats normally lasts 63 to 65 days (about two months or nine weeks), but can be as quick as 58 days and as long as 72 days. This pregnancy calculator for cats will calculate the most likely birth date using the mating date as a starting point.


Most likely birth date: June 21
Earliest birth date: June 14
Latest birth dates: June 28

Remember that these dates are estimates and that an incorrectly entered mating date can significantly affect the estimates.
