Cat Gestation Calculator
Select the mating date of your cat to find out the expected due date of the kittens.
Understanding Cat Pregnancy (Gestation)
The average gestation period for a cat is around 63 to 67 days, or approximately 9 weeks. Our Cat Gestation Calculator helps you estimate when your queen (female cat) is likely to give birth after mating. This allows you to monitor her health and prepare a warm, quiet nesting area for her kittens.
🧬 What Happens During a Cat’s Pregnancy?
After successful mating, the fertilized eggs implant into the uterus and develop into kittens over the next few weeks. Around week 3, physical signs such as enlarged nipples and morning sickness may appear. By week 5 or 6, you’ll notice weight gain and a visibly rounded belly.

📋 Common Signs of Pregnancy in Cats:
- Enlarged, pinkish nipples (also called “pinking up”)
- Increased appetite and rest time
- Morning sickness or vomiting
- Swollen belly (especially from week 5)
- Behavioral changes – more affectionate or hiding
🐾 Preparing for Kittens
By the last two weeks of pregnancy, the cat will start nesting. Prepare a clean, soft box or corner in a quiet part of the house. Ensure she has access to nutritious food and plenty of water. Keep her stress-free during this time for a smooth delivery.
📌 Tip:
If you’re unsure whether your cat is pregnant, consult a veterinarian. An ultrasound or X-ray can confirm the number of kittens and ensure a healthy pregnancy.
