1. Cat Pregnancy Duration

The average gestation period for cats is approximately 65 days (9 weeks) from conception to birth. This can vary slightly by breed, with some cats delivering as early as 58 days or as late as 70 days.

2. How the Calculator Works

The calculator uses the standard feline gestation period:

It then calculates:

• The expected due date
• Days remaining until birth
• Current pregnancy stage based on days remaining

3. Cat Pregnancy Stages

Details: Cat pregnancy progresses through three trimesters:

• Weeks 1-2: Early development, few visible signs
• Weeks 3-5: Nipple enlargement, weight gain, appetite increase
• Weeks 6-9: Visible abdominal enlargement, nesting behavior

4. Using the Calculator

Tips: Enter the known or estimated conception date. If unsure, use the mating date plus 1-2 days. For best accuracy, consult with a veterinarian for ultrasound confirmation.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is the 65-day estimate?
A: While 65 days is average, normal gestation can range from 58-70 days. First-time mothers often deliver closer to 65 days.

Q2: Can you tell how many kittens to expect?
A: This calculator doesn't predict litter size. A vet can estimate via palpation (after day 21) or X-ray (after day 45).

Q3: When should I take my cat to the vet?
A: Schedule a prenatal visit 3-4 weeks after conception. Watch for complications like prolonged labor (>24 hours) or discharge.

Q4: What affects gestation length?
A: Factors include breed (Siamese often longer), litter size (larger litters may come earlier), and maternal age.

Q5: How can I prepare for the birth?
A: Provide a quiet nesting box with clean towels 1-2 weeks before due date. Monitor temperature (drop may signal labor).
