Select the first mating date, last mating date, or estimated conception date. Most cat pregnancies last around 63 to 65 days, but normal delivery can vary by several days.
Formula used:
Estimated due date = selected date + gestation length
Earliest likely date = selected date + 61 days
Latest likely date = selected date + 67 days
Days pregnant = today – selected date
Days remaining = estimated due date – today
Estimated due date = selected date + gestation length
Earliest likely date = selected date + 61 days
Latest likely date = selected date + 67 days
Days pregnant = today – selected date
Days remaining = estimated due date – today
