How to Track Cat Pregnancy
Predict your cat's whelping schedule with these steps:
Log the Mating Date
Record the day the mating occurred. Use the midpoint if breeding occurred over multiple days.

Add 64 days to the mating date to establish the average due date.
Schedule Veterinary Checkups
A vet can confirm pregnancy via ultrasound around day 25-30, or feel kittens around day 35.
