The cats pregnancy calculator is an online tool that helps estimate cat’s due date, the average cats gestation is 63 days or 9 weeks or two months.

When a pregnant cat will give birth is always determined by its mating or breeding date. It uses the average feline gestation period to calculate a due date.

The formula is:

Due Date = Breeding Date + 63 days

Pet Cats have an average pregnancy length of 63-67 days. Feline due date calculator use 63 days from the approximate breeding date to estimate the kittens’ due date.

How to calculate my cat’s due date?

To calculate the due date:

1. Take the date your cat was bred – this is Day 1 of gestation.
2. Add 63 days to that date.
3. The date calculated is the estimated due date.

Cats go through a 9-week gestation period before giving birth to a litter of kittens. Knowing when your cat became pregnant and anticipating the birth can help you prepare.

To use a cat pregnancy calculator:

1. Enter the date your cat was first bred
2. The calculator estimates a due date 65 days from the first breeding, as cats have a typical gestation length of 63-67 days.

What information do you need to use a cat pregnancy calculator accurately?

• The exact date your cat was first bred, if known. If the date is unknown, estimate when your cat first went into heat and could have mated.
• Your cat’s breed, as some purebreds have slightly shorter or longer gestation periods.
• Dates of any subsequent matings, as kittens don’t always arrive precisely 65 days after the first breeding.

Cat pregnancy calendars provide an estimated due date based on the first day your cat mated. This useful for estimating the due date so you know when to expect those tiny paws.

How can I tell that my cat is Pregnant?

Some signs that indicate your cat may be expecting kittens include:

• Weight gain and enlarging nipples 1-2 weeks after mating
• Enlarged, pink nipples 3-4 weeks after mating

Cats can get pregnant again very quickly after giving birth, as early as 2 weeks after delivery. This is because feline estrus cycles resume shortly after birth.
