How long does pregnancy last and how many kittens will by cat have are two of the most common questions cat owners have. The regular gestation period for cats is between 58 and 65 days, or approximately 9 weeks. A queen (pregnant cat) may have anywhere from 1 to 8 kittens at a time.
When the contractions become more frequent, the birth of the first kitten will normally happen within 20 minutes. The next kittens may come out in rapid succession or in longer intervals. In some cases, the entire delivery process of all the kittens could even last as long as 24 hours, especially for larger litters.
