Understanding cats pregnancy stages is essential for any pet owner expecting kittens. A cat’s pregnancy, also known as gestation, lasts between 63 to 67 days (about 9 weeks) and is divided into distinct stages. During this period, your cat undergoes significant physical and behavioral changes. In this in-depth guide, we’ll break down the different stages of a cat’s pregnancy, what to expect, and how to care for your pregnant feline.
How to Tell If Your Cat Is Pregnant
Before diving into the stages, it’s crucial to confirm your cat’s pregnancy. Some common signs include:
✅ Increased Appetite – Your cat may start eating more than usual.
✅ Nipple Changes – Nipples become larger and pinker (called “pinking up”).
✅ Behavioral Changes – More affectionate or, in some cases, withdrawn.
✅ Weight Gain – A steady increase in weight as pregnancy progresses.
✅ Swollen Abdomen – Noticeable belly growth after 3-4 weeks.
✅ Less Frequent Heat Cycles – If your cat’s heat cycle stops, she may be pregnant.
If you suspect pregnancy, visit a veterinarian for confirmation through ultrasound or palpation.
Cats Pregnancy Stages: Week-by-Week Breakdown
A cat’s pregnancy is typically divided into five key stages, each bringing new developments.
1. Fertilization & Early Pregnancy (Week 1-2)
- After mating, sperm fertilizes the eggs in the female’s uterus.
- The fertilized eggs travel to the uterus and implant in the uterine lining.
- Hormonal changes begin, but there may be no visible signs of pregnancy yet.
🔹 What to Expect:
- Your cat may continue her normal routine with no behavioral changes.
- Early hormonal shifts might cause mild nausea, leading to reduced appetite.
👩⚕️ Care Tips:
- Continue feeding her a normal, high-quality diet.
- Avoid giving medications unless prescribed by a vet.
2. Embryonic Development (Week 3-4)
- Embryos begin forming inside the uterus, and hormone levels rise significantly.
- The “pinking up” of nipples (nipples turning pink and becoming swollen) occurs.
- Your cat may start experiencing morning sickness, leading to occasional vomiting.
🔹 What to Expect:
- A slight increase in appetite.
- Mild weight gain and abdominal enlargement.
- Some cats become more affectionate, while others may be more withdrawn.
👩⚕️ Care Tips:
- If your cat experiences morning sickness, offer small, frequent meals.
- Limit stress and ensure she has a quiet, comfortable space.
- Consult your vet for a pregnancy confirmation ultrasound.
3. Mid-Pregnancy (Week 5-6)
- The kittens’ organs and skeletons develop, and the mother cat’s belly becomes noticeably larger.
- Her appetite significantly increases as she needs extra nutrition for the growing kittens.
- You might start feeling small fetal movements inside her belly.
🔹 What to Expect:
- A rounded belly that continues to expand.
- Increased weight gain (around 2-4 pounds, depending on litter size).
- Nesting behavior may begin—your cat may seek out quiet, cozy spots.
👩⚕️ Care Tips:
- Switch to high-quality kitten food (rich in protein and calcium).
- Provide a warm nesting area in a quiet part of your home.
- Keep her indoors to prevent stress and accidental exposure to male cats.
4. Pre-Labor & Final Growth Stage (Week 7-8)
- The kittens are almost fully developed and will double in size in the final weeks.
- Your cat will become less active as carrying the extra weight becomes tiring.
- Increased nesting behavior—she might start kneading blankets or hiding in secluded areas.
🔹 What to Expect:
- Enlarged mammary glands that may start producing milk.
- Restlessness, pacing, or searching for a comfortable birthing spot.
- She may groom excessively, especially around her belly.
👩⚕️ Care Tips:
- Offer smaller, frequent meals as a large belly may reduce stomach capacity.
- Ensure she has a soft, safe birthing area, such as a box lined with towels.
- Avoid unnecessary handling as she may become easily irritated.
5. Labor & Birth (Week 9 – Delivery Day)
- Labor usually begins within 58-67 days, though some cats may deliver a little earlier or later.
- There are three stages of labor:
Stage 1: Pre-Labor (12-24 Hours Before Birth)
- Your cat may appear restless, vocal, or anxious.
- Her body temperature drops slightly.
- She may refuse food and start panting.
Stage 2: Active Labor & Kitten Delivery
- Contractions begin, and kittens are born at 15-60 minute intervals.
- The mother will lick each kitten to stimulate breathing and remove the birth sac.
- The placenta is expelled after each kitten.
Stage 3: Post-Labor Recovery
- Once all kittens are born, the mother rests and begins nursing.
- Ensure all kittens are breathing and feeding properly.
👩⚕️ Care Tips:
- Do not interfere unless necessary. Most cats handle birth instinctively.
- If labor lasts more than 24 hours or if she struggles with a kitten for over 1 hour, call a vet immediately.
- Make sure each kitten nurses within the first few hours to receive colostrum (nutrient-rich milk).
