Cat Pregnancy Calculator
Enter the date your queen was mated to estimate her due date and queening stage. This cat pregnancy calculator uses a 65-day guide for most cats.
Pick the key mating date. If she called and mated on several days, choose the day you think ovulation was closest to.
How this cat pregnancy calculator works
Many queens carry kittens for about 65 days from conception, with a normal range either side. The calculator adds 65 days to your mating date and shows an estimated queening day.
It also reports how many days pregnant your cat is today and how many days remain until the due date. A stage label and care tip help you plan nesting spots, food, and vet checks more calmly.
Frequently Asked Questions
The result is only a guide. Ovulation timing, litter size, and breed can shift queening a few days earlier or later than the date shown.
You can use the first strong mating, the last, or the middle day and then treat the due date as a window. Ultrasound and vet checks can refine the timing further.
Many breeders plan at least one vet visit for scans or health checks. Contact your vet sooner if your queen seems unwell, stops eating, or goes past the due window with no sign of labor.
