Understanding the Gestation Period of Your Feline Friend: A Guide to Using the Cat Pregnancy Calculator

As a cat owner, it's natural to have questions about your feline friend's pregnancy and the arrival of their kittens. Using a cat pregnancy calculator can help you understand the gestation period of your cat and provide you with important information about the arrival of your furry little bundles of joy.
In this guide, we will cover how to calculate your cat's due date, how to use the cat pregnancy calculator, how many days a cat is pregnant, how to tell how far along your cat is, and whether you can feel kittens in a pregnant cat. We will also address frequently asked questions about cat pregnancy.

How to Calculate My Cat's Due Date

To calculate your cat's due date, you can use the following equation: Cat due date = Mating date + 63 days. It's important to note that the healthy due date for your cat is actually a range, between 58-71 days after mating.
If you're unsure of your cat's mating date, you can visit a veterinarian for help or try using other methods to estimate the gestation period (more on that below).

How to Use the Cat Pregnancy Calculator

Using the cat pregnancy calculator is simple. Just enter your cat's estimated mating day and the calculator will provide you with the exact delivery date, as well as the range of possible delivery dates.

How Many Days Is a Cat Pregnant?

The gestation period for a cat can range from 58-71 days, with the average being 63 days. If you know your cat's mating date, you can use the equation provided above to calculate their due date.

How to Tell How Far Along Your Cat Is

There are several ways you can determine how far along your cat is in their pregnancy. One way is to visit a veterinarian, who can assess your cat's condition and provide you with an estimated due date. You can also try the following methods:
  • Examining your cat's nipples: Within 15-18 days of pregnancy, your cat's nipples will become swollen and turn red or dark in color.
  • Observing the size of your cat's belly: After 2-3 weeks of pregnancy, your cat's belly will start to enlarge and they may gain up to 2 extra kilograms (4.4 lb).
  • Counting missed heats: A healthy female cat will experience heat (a period of increased fertility) every 2-3 weeks. If you are familiar with your cat's behavior, you can count the number of heats they have missed to estimate their pregnancy.
  • Can You Feel Kittens in a Pregnant Cat?

    While it may be tempting to touch your cat's belly, it's important to avoid doing so as it could potentially harm both the mother and the kittens.
