What's going on: Your baby is moving down the birth canal. Contractions continue to be strong, lasting for about 60 seconds and coming 3 to 5 minutes apart. You will likely feel a strong urge to push. How long it lasts: 1 to 2 hours for a first labor; 15 to 30 minutes for subsequent labors. If your baby is in distress at this point, or if she doesn't seem to be making her way through the birth canal, your doctor may decide to deliver her by c-section or use forceps to help her out.
Strong Contractions in the Second Stage. The second stage of labor begins with the birth of the first kitten, which should happen around 30 minutes to an hour after Fluffy starts her strong contractions. She'll have rest times between each kitten's birth, usually lasting about 15 to 30 minutes. Depending on how many kittens there are, it can take as little as a couple of hours to a good part of a day for Fluffy to deliver her brood.
