How to calculate my cat's due date?

Here's the equation that will allow you to write down your cat's pregnancy week by week:

Cat due date = Mating date + 63 days

Remember that Mother Nature is not as accurate as math — the healthy due date of your cat is actually a range and may be between 58-71 days after mating.

As you can see, calculating your cat's due date is not tricky at all — you may use our ready-to-go cat gestation calculator or compute it all by yourself. 🐱

How to tell how far along your cat is?

There are multiple ways to assess your cat's pregnancy length — the easiest one is to visit your vet, since the enlargement of your cat's tummy might also be a sign of a severe disease.

Let's see other home methods we can use by observing cat pregnancy day by day:

  1. Assessing your cat's nipples

    Your cat's nipples will become swollen and turn red/dark in color within the 15-18 days of the pregnancy.

  2. Enlarged tummy

    The tummy of a future mum enlarges after 2-3 weeks of the pregnancy. Your cat baby will also start to gain weight — even up to 2 extra kilograms (4.4 lb)!

  3. Heat is missing

    A healthy female cat has the heat (a period of increased fertility) every 2-3 weeks. If you know your cat's behavior pretty well, you can count how many of the heats she's already missed.

Can you feel kittens in a pregnant cat?

Touching the pregnant cat's belly may seem appealing, but you need to avoid doing that — in a worst-case scenario, such an action can hurt both the mother and the babies!

After just a few weeks, we can feel something similar to the beads chain in a cat's belly — these are young kittens starting to grow! Later on, you can clearly feel separate kittens and even see them moving.
