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.
This stage is the big time! Now your pregnant cat will start to have major contractions. She will be breathing deeply and you will see visible movement and shuddering of her belly. In the beginning, the contractions for cats giving birth to kittens may be once every 30 minutes and possibly longer.irst Stage of Labor. The first sign of labor for cats giving birth to kittens is restlessness with some growling or rhythmic purring. You might also be able to observe some shallow and rapid breathing, and possibly a slight flaring of your kitty's nostrils during the beginning faint contractions.
