Cats are pregnant for about two months, with the gestation period averaging 63 to 65 days (roughly nine weeks)

. When it comes to giving birth:

• The labor process usually takes between 4 to 16 hours, but it can sometimes last longer

• Most cats deliver their entire litter within about six hours after labor starts, though the process can extend up to 12 hours in some cases

• Kittens are typically born at intervals ranging from 10 minutes to an hour, with the mother delivering each kitten followed by the afterbirth

• If more than 3 hours pass between kittens, or if the cat strains for 20-30 minutes without delivering a kitten, veterinary assistance should be sought

In summary, cats carry their kittens for about two months and usually give birth over a period of several hours, often completing delivery within six hours but sometimes taking up to 12 or more hours depending on the number of kittens and other factors
