Frequently Asked Questions
How long is a cat pregnancy?
A cat pregnancy averages 63 days, about 9 weeks, from mating to birth, with a healthy range of 58 to 71 days.
Why is there a range instead of one exact date?
Individual cats vary in gestation length, so the due date is genuinely a range rather than one precise day, similar to how human due dates are also estimates.
Should I contact a veterinarian as the due date approaches?
Yes, having a veterinarian available as the estimated range approaches is recommended, particularly for a first pregnancy or any signs of prolonged or difficult labor.
