A Cat Pregnancy Calculator is a valuable tool that helps cat owners determine their pet’s due date by providing an accurate estimation based on key dates during the cat’s pregnancy.
From knowing the stages of your cat’s pregnancy to preparing for the arrival of kittens, this guide covers everything you need. If you’re looking to calculate your cat’s due date, learn about the cat gestation period, and ensure proper care for your pregnant feline, you’re in the right place.

Cat Pregnancy Calculator
Wondering when your cat is due to give birth? Use our simple Cat Pregnancy Calculator below to estimate your cat’s due date. A cat’s pregnancy (gestation) typically lasts between 63 to 65 days.
Note: This is an estimate only. Always consult with a veterinarian for accurate care and guidance.
How to Use a Cat Pregnancy Calculator
What Is a Cat Pregnancy Calculator?
A Cat Pregnancy Calculator is a tool designed to estimate your cat’s due date based on her gestation period. By entering the date your cat mated or was confirmed pregnant, you can calculate an approximate delivery date to prepare for the arrival of the kittens.
This tool simplifies the process by taking into account the standard cat gestation period (approximately 63–65 days) to predict when your queen (a term used for pregnant cats) will go into labor.
Step-by-Step Guide to Calculate Cat Due Date
- Input the Date of Mating: The first step is to note down the date when your cat mated or was confirmed pregnant by the vet.
- Use the Calculator: Enter the mating date into the calculator, and it will automatically add 63–65 days to provide an estimated due date.
- Review the Results: With the calculated due date, you can now track your cat’s pregnancy stages and prepare accordingly.
For example, if your cat mated on June 5th, her kittens would likely be born between August 7th and August 10th.

Benefits of Using a Cat Pregnancy Calculator
- Accurate Planning: It allows you to prepare in advance for the kittens’ arrival.
- Health Monitoring: You can track your cat’s progress through all pregnancy stages.
- Peace of Mind: Knowing the timeline reduces guesswork and stress for owners.
Understanding the Cat Gestation Period
How Long Is a Cat’s Gestation Period?
The average cat gestation period is 63–65 days, though it can vary slightly depending on factors like the cat’s age, breed, and health. Tracking this timeline ensures you know what to expect and when to expect it.
Factors That Can Affect Gestation Length
While most cats follow the standard timeline, a few variables can impact the gestation period, including:
- Breed: Certain breeds, such as Siamese cats, may carry slightly longer.
- Age: Younger or older cats might have irregular timelines.
- Health Conditions: Underlying health issues can lead to shorter or extended pregnancies.
Key Milestones in a Cat’s Pregnancy
A typical cat pregnancy can be divided into three main stages:
- Early Pregnancy: Hormonal and behavioral changes occur.
- Mid-Term Pregnancy: Physical changes, such as a rounded abdomen, become apparent.
- Late Pregnancy: Nesting behavior and pre-labor symptoms are observed.
Understanding these stages helps you provide appropriate care during each phase.
Cat Pregnancy Stages
Stage 1 – Early Pregnancy (Weeks 1–2)
During the early stages, it’s not always apparent your cat is pregnant. However, you might notice behavioral changes like increased affection, decreased activity, and subtle weight gain.
Stage 2 – Mid-Term Pregnancy (Weeks 3–6)
Around the third week, physical signs like a swollen belly and enlarged nipples (known as “pinking up”) appear. Cats in this stage may have an increased appetite, so offering nutrient-rich food is critical.
Stage 3 – Late Pregnancy/Pre-Labor (Weeks 7–9)
During the final weeks, your cat might start nesting, seeking out quiet, comfortable spots to give birth. Her appetite may decrease as labor approaches, and signs like restlessness, pacing, or vocalizing may emerge just before delivery.
Pregnant Cat Care Tips
Proper Nutrition for Pregnant Cats
Offer balanced, nutrient-dense food to support your cat’s increased energy needs. Many vets recommend switching to kitten food during pregnancy as it provides extra calories and essential nutrients.
Creating a Comfortable Environment
Designate a quiet, low-traffic area for your cat with a soft blanket or bedding. This safe zone will serve as her nesting area when she’s ready to give birth.
Monitoring Health and Veterinary Checkups
- Schedule regular vet visits to monitor the pregnancy’s progress.
- Watch for warning signs, such as vomiting, lethargy, or discolored vaginal discharge, which may indicate complications.
Preparing for Kitten Birth
Supplies You’ll Need for Kitten Delivery
Prepare these essential items to ensure a smooth birthing process:
- A quiet, clean birthing box
- Soft towels to keep the kittens warm
- A heating pad (set on low) to help them regulate body temperature
- Gloves and sterile scissors (for emergencies)
How to Identify Labor Signs in Cats
Common labor signs include:
- Increased grooming
- Restlessness and pacing
- Low, soft vocalizations
- Visible contractions
When you notice these signs, give your cat privacy and monitor from a distance.
Post-Birth Care for Mother and Kittens
- Ensure the mother starts nursing within the first few hours after delivery.
- Keep the area warm and dry to prevent health issues for both mother and kittens.
- Monitor the kittens daily for signs of growth and activity.
