Discover the cat pregnancy timeline, from early signs to key stages, and learn how to support your furry friend during this exciting journey.

Your cat is pregnant—congratulations! But now you’re wondering, what comes next? Understanding a cat’s pregnancy timeline can feel overwhelming at first, especially if this is your first experience caring for a pregnant feline. Knowing what to expect during each stage will help you provide the best care for your furry friend and her soon-to-arrive kittens.

🩺 Vet Recommendations

Pregnancy in cats, also called the gestation period, lasts about 63–65 days on average, though it can range from 58 to 70 days. During this time, your cat will go through several stages, each with its own signs and care requirements. As a pet owner, your role is to monitor her health, adjust her diet, and prepare for the arrival of her kittens.

Here’s a breakdown of the key stages of a cat’s pregnancy timeline and how to care for her at each step.

📋 Care Tips

1. Week 1–2: Fertilization and Early Pregnancy

Pregnancy begins once your cat has successfully mated, and fertilization occurs. At this stage, there are often no obvious physical signs of pregnancy. However, you might notice subtle behavioral changes, such as increased affection or slightly reduced energy levels.

  • Keep your cat indoors to ensure her safety and prevent additional mating attempts.
  • Continue her regular diet and routine unless advised otherwise by your vet.

2. Week 3–4: Early Development

By the third week, the embryos begin to develop in your cat’s uterus. You may start to notice physical signs, including slight weight gain and enlarged nipples, which may appear pinker (a phenomenon called "pinking up"). Morning sickness can also occur during this period.

  • Offer small, frequent meals if your cat experiences nausea or reduced appetite.
  • Avoid handling your cat’s abdomen to prevent harming the developing embryos.

If you’re unsure whether your cat is pregnant, your vet can confirm it via an ultrasound or physical exam around the 21-day mark.

3. Week 5–6: Noticeable Changes

By the fifth week, your cat’s pregnancy becomes more apparent. Her belly will start to swell as the kittens grow, and her appetite will likely increase. This is an important time to switch her to a high-quality kitten food, which provides the extra nutrients she needs for her growing babies.

  • Gradually transition her to kitten food over 7–10 days to avoid stomach upset.
  • Provide plenty of fresh water to keep her hydrated.

4. Week 7–8: Preparing for Birth

During the final weeks of pregnancy, your cat will show significant weight gain, and you may even feel the kittens moving if you gently place your hand on her belly. She may start "nesting," seeking out quiet, safe spaces to give birth.

  • Set up a comfortable nesting area with soft blankets in a quiet corner of your home.
  • Keep her environment calm and stress-free to ensure her comfort.

If you haven’t already, schedule a prenatal check-up with your vet to ensure everything is progressing smoothly.

5. Week 9: Labor and Delivery

As your cat approaches her due date, she may become restless, vocal, or clingy. These are signs that labor is imminent. When she’s ready to give birth, she’ll settle in her nesting area and begin delivering her kittens. Labor typically lasts 6–12 hours but can take longer for first-time moms.

Signs of labor include:

  • Drop in body temperature (below 100°F)
  • Increased vocalization or panting
  • Visible contractions

It’s best to observe quietly from a distance unless your cat seems to be struggling. If labor lasts more than 24 hours or a kitten is stuck, contact your vet immediately.

✅ Do’s and Don’ts

  • Do provide a safe, quiet space for your cat to rest and give birth.
  • Do feed her a high-quality kitten food throughout pregnancy and nursing.
  • Do monitor her for any signs of distress or complications.
  • Don’t handle newborn kittens unnecessarily, as this can stress the mother.
  • Don’t give your cat medications or supplements without consulting your vet.
