Cat Pregnancy Calculator
Track your cat’s pregnancy journey from breeding date to delivery with key milestones and care tips.
Note: Cat pregnancy (gestation) typically lasts between 58-67 days, with an average of 63-65 days. This calculator uses the 64-day average for calculations.

Nutrition Tips
Feed kitten food during the last 3-4 weeks as it’s higher in calories, protein, and calcium. Increase food by 25-50%.
Vet Care
Schedule a vet visit 2-3 weeks after breeding for confirmation. An ultrasound can detect kittens around day 21.
Nesting Box
Prepare a quiet, warm nesting box around week 7. Use clean towels or blankets that can be easily washed.
Signs of Labor
Watch for restlessness, vocalizing, loss of appetite, and temperature drop (below 100°F) 12-24 hours before labor.
Cat Pregnancy Calculator: Your Week-by-Week Guide to Kitten Arrival
Is your feline friend showing signs of expecting? Just like human parents, cat owners often feel a mix of excitement and anticipation. A cat pregnancy calculator is your go-to tool for demystifying this special time, helping you prepare for the big day with confidence.
What Is a Cat Pregnancy Calculator?
Think of it as your feline due date estimator. By entering the first known date of mating (or your best guess), the calculator uses the average feline gestation period—63 to 67 days—to predict a due date range. This simple tool transforms uncertainty into a clear timeline, allowing you to provide the best care.
Why Using a Calculator Matters for Cat Owners
Knowing the approximate due date is more than just marking the calendar. It lets you:
· Prepare a “Kitten Nursery”: Set up a quiet, comfortable nesting box in advance.
· Schedule a Vet Visit: Confirm the pregnancy and get tailored dietary advice.
· Monitor Her Health: Track her weight gain and look for specific week-by-week changes.
· Plan Your Time: Ensure you or someone can be nearby as the due date approaches.
How to Use It Effectively
Since cats can mate multiple times, pinpointing the exact conception day can be tricky. If the mating date is unknown, note when you first noticed behavioral changes—like increased affection or a paused heat cycle—and use that as a starting point. The calculator will give you a window, not an exact day, which is perfectly normal in feline pregnancy.
Your Weekly Milestones Guide
A good calculator often pairs dates with a developmental guide:
· Weeks 1-3: Subtle changes. Her nipples may become more prominent (“pinking up”).
· Weeks 4-5: A veterinarian can confirm pregnancy. Her appetite will increase.
· Weeks 6-7: Visible weight gain and clear abdominal rounding.
· Week 8+: Nesting behavior begins. She may seek out secluded spots.
Remember, a cat pregnancy calculator is a planning helper, not a substitute for veterinary care. Always consult your vet to ensure a healthy pregnancy. With this tool and professional guidance, you’re well-equipped to welcome a healthy litter and support the new cat mom every step of the way.
