* Kitten Delivery: Kittens are typically born in a "burst" or "wave" within a few hours of each other. This is because the contractions that push out kittens are very strong and often happen close together.
* Feline Labor: A queen (female cat) will often have contractions for several hours before the first kitten is born. Once the first kitten is out, the rest usually follow quickly.
* Exceptions: There are a few rare exceptions:
* Large Litters: With exceptionally large litters (10+ kittens), there might be a short break between some kittens as the queen needs to recover.
* Complications: If there are complications like a kitten stuck in the birth canal, it might delay the birth of subsequent kittens.
If you are concerned about a queen giving birth, it's best to consult a veterinarian. They can monitor the situation and ensure both the mother and kittens are healthy.
