Frequently Asked Questions
The average feline gestation period is 63 to 67 days, with most cats delivering around day 65. Visible signs of pregnancy, such as pinking of the nipples, typically appear around week 3 to 4. By week 5, a veterinarian can often feel kittens in the abdomen, and an ultrasound can confirm pregnancy as early as day 21 to 28.
Schedule a veterinary visit around 3 weeks after mating to confirm the pregnancy and assess overall health. Regular checkups throughout gestation help monitor the queen's weight, nutrition, and kitten development. Contact your vet immediately if you notice signs of complications such as prolonged vomiting, lethargy, discharge, or if labor lasts more than a few hours without producing kittens.
The average litter size for cats is 4 to 6 kittens, though this can vary significantly depending on breed and the queen's age. First-time mothers often have smaller litters of 2 to 3 kittens, while mature cats may have larger litters. An X-ray or ultrasound in the later weeks of pregnancy can provide a more accurate count.
