Calculating Cat Pregnancy and Due Date: A Quick Guide

Part 1: How to Accurately Determine a Cat's Due Date

During the pregnancy of a cat, it's essential to provide adequate nutrition to support the health of both mother and kittens.

When calculating the due date for a cat, it's generally estimated to be around 64 days from the day of mating. It's important to note that cats do not ovulate directly during their heat cycle; rather, they only release eggs after mating. This is when sperm and eggs combine to form fertilized eggs, marking the beginning of the pregnancy.

However, for practical purposes, we typically start counting from the day after successful mating, which means the average gestation period for cats is about 63 days. The actual due date can vary depending on the cat's breed and constitution. For instance, longhaired cats and purebred cats may have a gestation period that is 12 days longer than the average, while shorthaired cats and domestic shorthairs might have a due date that is 12 days shorter. If the litter size is larger, the due date may be slightly shorter, whereas a smaller litter size can lead to a longer gestation period. Overall, the discrepancy usually does not exceed 7 days. If your cat shows no signs of labor after 65 days of pregnancy, it's advisable to consult a veterinarian to rule out false pregnancy or signs of dystocia.

Part 2: Important Considerations for a Pregnant Queen Cat

1. Ensure proper nutrition during pregnancy to prevent developmental issues in the kittens or difficulties in labor due to the mother's exhaustion. However, avoid overfeeding, as excessive weight gain can complicate the birthing process. It's best to follow a balanced feeding schedule.

2. Encourage moderate exercise before the due date, especially during the early stages of pregnancy when the belly is not yet very prominent. Lack of exercise can increase the risk of miscarriage, so keep your cat active but not overly stressed.

3. Be patient and attentive during the twomonth gestation period. Your cat needs your care and reassurance to feel secure and comfortable.

4. Pay close attention to the due date, as premature labor before 58 days can result in underdeveloped kittens with weak cries and lower survival rates. Delayed labor beyond the due date can lead to rupture of the amniotic fluid and stillbirth. Be prepared for the birthing process when the time comes.

5. A significant drop in body temperature by about 1℃ in the 24 hours before delivery is a common sign. The temperature may then rise by 0.51℃ as labor approaches. A kitten should be born within 14 hours after the cat starts to strain. If not, this could indicate dystocia.
