Find Out When Your Cat Will Have Kittens

Wondering when your cat might give birth? Our Cat Pregnancy Calculator helps you quickly estimate your cat’s expected due date based on the day she first mated. Most cats are pregnant for about 63 to 67 days, though some may give birth a few days earlier or later depending on breed, age, and overall health.

Simply enter the date of your cat’s mating below, and the calculator will show you a range of possible delivery dates, from the earliest possible to the most likely time frame.

🐾 How to Use the Cat Pregnancy Calculator

Using this calculator is super simple, just follow these quick steps:

Select the date your cat first mated using the calendar input.
Click on the “Calculate” button.
The tool will instantly show you:
- The earliest possible due date
- The most likely birth range
- The latest possible date your cat could deliver
Use the results to plan ahead, prepare a cozy nesting spot, gather kitten supplies, and monitor your cat’s health.

💡 Tip: Cat pregnancy typically lasts around 63–67 days, but some queens may deliver a few days earlier or later. Always consult your vet for confirmation and guidance.

Understanding Cat Pregnancy Duration

The average cat pregnancy lasts about 9 weeks (roughly 63 days). However, it can vary slightly:

Short pregnancies (58–62 days) – often happen in smaller breeds or first-time mothers.
Typical pregnancies (63–67 days) – the most common range.
Longer pregnancies (up to 72 days) – still normal for some cats, especially larger breeds.

During this time, you may notice signs like:

Increased appetite and affection
Slightly enlarged nipples
Gentle weight gain and visible belly swelling
Nesting behavior as birth approaches

What to Expect Each Week of Cat Pregnancy

Week	What Happens	Care Tips
1-2	Fertilization and early development	Keep her calm and well-fed
3-4	Abdomen starts to round slightly	Avoid unnecessary handling
5-6	Belly becomes more visible; nipples darken	Offer a cozy nesting spot

9	Labor signs appear	Stay prepared for delivery day!

How Accurate Is This Cat Pregnancy Calculator?

This calculator provides an estimated timeline, based on the typical feline gestation period. Every cat is unique, and birth may occur a few days before or after the predicted range.

For exact confirmation, your veterinarian can perform an ultrasound or X-ray around day 40–45 of pregnancy to determine the number of kittens and the health of the mother.

💡 Tip: Start preparing your cat’s birthing area around day 60 to make sure she’s comfortable and stress-free.

Caring for a Pregnant Cat

Here are a few essentials to support your expecting queen:

Provide a high-quality, protein-rich diet
Keep her indoors to avoid stress or accidental injuries
Offer a quiet nesting area away from noise and activity
Schedule regular vet checkups

Once the kittens arrive, ensure they’re warm, nursing, and gaining weight properly.
