Between the time that they have they're first kitten & last. She's already had three but I had read online that sometimes they're is pauses but not to mistake them for the ending of labor. So what on average does everyone know time wise? She had her first kitten about five hours ago. It does not take six weeks between the time she has her first kitten to her last kitten when she goes into labor. I'm not asking how long they are pregnant for. I'm asking how long the labor lasts from the first kitten to the last.
