How Our Cat Pregnancy Calculator Works - Live Minutes

Our veterinarian-approved Cat Pregnancy Calculator calculates your cat's due date from her first mating date. Cats have a short gestation of 63-67 days, average 65 days. Unlike dogs, cats are induced ovulators. Our tool adds 65 days to the mating date to find the due date, and shows a safe window from Day 63 to Day 67. It also has a Live Minutes Counter that ticks every minute, showing exactly how many minutes your cat has been pregnant. It auto-saves your date so when you return, it continues live.

Why We Show USA & Europe Date Format?

Date confusion can cause missed vet appointments. USA uses MM/DD/YYYY (05/13/2026) and Europe/UK uses DD/MM/YYYY (13/05/2026). Our calculator solves this: Input box shows your local format automatically. Output always shows May 13, 2026 format which is clear for USA and Europe both. For Google SEO we use ISO 2026-05-13. This makes it 100% Google-friendly and user-friendly.
