A cat pregnancy lasts about 65 days from the breeding date, which is 9 weeks and 2 days; most births fall between day 60 and day 67. Day 0 is the breeding date, so week 1 is days 0 to 6, week 2 is days 7 to 13, and so on.

Week by week: days and dates
Dates for a cat bred on Mar 1, 2027. Pick your own breeding date in the calculator above.
Day 65: Due date (kittening) · Day 67: Latest usual date
Week 1 (days 0–6): breeding
Day 0 is the breeding date. If she was bred on several days, the calculator counts from the first breeding and the usual window runs to the last breeding + 67 days.
Cats ovulate when they mate, so a queen bred on several days is usually counted from the first breeding. Pregnancy ranges from about 60 to 67 days (VCA Animal Hospitals).
Weeks 2 to 4 (days 7–27)
Nothing on the schedule until day 32 (halfway, week 5). By day 27, 38 days are left to the due date.
Week 5 (days 28–34): halfway
Day 32 (Apr 2, 2027) is halfway through a 65-day pregnancy. From here, 33 days are left to the due date.
Weeks 6 to 8 (days 35–55)
Nothing on the schedule until day 58 (a week to go, week 9). By day 55, 10 days are left to the due date.
Week 9 (days 56–62): a week to go and the usual window opens
Day 58 (Apr 28, 2027) is one week before the due date. The schedule’s reminder for this day: get a clean, quiet birthing area ready.
Day 60 (Apr 30, 2027) is the earliest usual date: from here on, a birth is inside the usual range.
Week 10 (days 63–67): the due date and the usual window closes
Day 65 (May 5, 2027) is the due date, the average length counted from breeding. It is an estimate; most births fall between day 60 and day 67.
Day 67 (May 7, 2027) is the latest usual date. If that day passes, or anything about the mother worries you, call your veterinarian.
