Cat Gestation Period

Cat gestation period varies from cat to cat - much like humans!



The average gestation period for cats is about 65 days, with most lasting between 63 and 67 days. Having said that, cat pregnancy can last anywhere between about 57 and 70 days.

An easy way to remember the gestation period of a cat is to think of each week of cat pregnancy as equivalent to a month of human pregnancy. So, 9 weeks of a cat pregnancy is 63 days (equivalent to 9 months of a full-term human pregnancy).

Even if you know when your cat mated, you can't predict exactly when the kittens will be born... Mommy cat will give birth when she's ready and not a moment before! But at least if you know the average time, you can get a rough idea of when to expect and prepare for the new arrivals.

The table below gives a list of due dates, based on a 65 day gestation period. Alternatively, click here for a kitten due date calculator.
