MD = Mating Date
| From: | To: |
The Cat Breeding Calculator estimates the due date for pregnant cats based on the mating date. The average gestation period for cats is approximately 63 days.
The calculator uses the simple formula:
Where:
Explanation: The calculation adds 63 days to the known or estimated mating date to predict when the queen will give birth.
Details: Knowing the expected due date helps breeders and owners prepare for the birth, monitor the queen's health, and recognize if the pregnancy goes beyond normal duration.
Tips: Enter the known or estimated mating date. The calculator will show the expected due date 63 days later.
Q1: How accurate is the 63-day gestation period?
A: While 63 days is average, normal gestation can range from 58-72 days. Monitor your cat closely as the due date approaches.
Q2: When should I start preparing for the birth?
A: Prepare a nesting box by day 50-55. The queen will typically start nesting behavior 1-2 weeks before delivery.
Q3: What if I don't know the exact mating date?
A: Use the earliest possible date of conception. Ultrasound can help estimate gestation age if the mating date is unknown.
Q4: Are there signs that birth is imminent?
A: Signs include nesting behavior, appetite loss, temperature drop (below 100°F), and restlessness about 24 hours before birth.
Q5: When should I be concerned about a late delivery?
A: Consult a veterinarian if the queen goes beyond day 65 without showing signs of labor, as this may indicate complications.
