Cat Pregnancy Calculation:
| From: | To: |
The average gestation period for cats is approximately 65 days (range 63-67 days) from the date of breeding. This calculator helps estimate when your cat is likely to deliver her kittens.
The calculator uses the standard cat gestation formula:
Note: While 65 days is the average, some cats may deliver a few days earlier or later. First-time mothers often deliver closer to 63 days.
Early signs (2-3 weeks): Pinkening of nipples, increased appetite, possible morning sickness
Mid-pregnancy (4-5 weeks): Noticeable weight gain, abdominal enlargement
Late pregnancy (6+ weeks): Visible kitten movement, nesting behavior, milk production
Instructions: Enter the known or estimated breeding date. The calculator will show the expected due date 65 days later.
Q1: How accurate is this calculator?
A: It provides an estimate based on average gestation. Individual cats may vary by ±2-3 days.
Q2: What if I don't know the exact breeding date?
A: Use the earliest possible date and monitor for signs of impending labor starting at 60 days.
Q3: When should I take my cat to the vet?
A: Schedule a prenatal checkup 3-4 weeks after breeding, and watch for complications like prolonged labor (>24 hours).
Q4: Can cats have false pregnancies?
A: Yes, some cats show pregnancy signs without actually being pregnant. Ultrasound can confirm pregnancy.
Q5: How many kittens can I expect?
A: Average litter size is 4-6 kittens, but can range from 1-12 depending on breed and age.
