1. Hormonal Changes:
* Progesterone levels decline: This triggers the release of other hormones like oxytocin and prostaglandins, which initiate contractions.
* Estrogen levels rise: This contributes to uterine contractions and cervical dilation.
2. Physical Signs of Labor:
* Nest building: The cat may start preparing a nest, seeking out a safe, quiet, and warm place to give birth.
* Restlessness: She might become more agitated, pacing, and vocalizing.
* Temperature drop: The cat's body temperature can drop by 1-2 degrees Fahrenheit in the 24 hours leading up to labor.
* Water breaks: A clear or slightly bloody discharge from the vulva indicates the amniotic sac is breaking.
* Contractions: These become more frequent and intense, starting as gentle waves and becoming stronger and more consistent.
3. Stages of Labor:
* Stage 1: This stage involves the onset of labor, with mild contractions and cervical dilation. It can last from a few hours to a day or more.
* Stage 2: This is the active birthing stage, characterized by strong contractions and the expulsion of kittens.
* Stage 3: This stage involves the expulsion of the placentas after each kitten is born.
Important Note: It's crucial to monitor the mother cat during labor. Contact your veterinarian immediately if you notice any unusual signs such as:
* Excessive bleeding
* Lack of progress in labor
* Signs of distress in the mother cat
* The kitten getting stuck in the birth canal
If you're expecting a new litter of kittens, it's essential to have a plan for the birthing process. This includes:
* Having a safe and comfortable nesting area prepared.
* Knowing the signs of labor and what to do if things don't go as expected.
* Having a veterinarian on call in case of emergency.
Remember: Every cat is different, and the labor process can vary. It's best to consult with your veterinarian if you have any concerns or questions about your cat's pregnancy and labor.
