Cat Pregnancy Calculator & Due Date
Enter the date your cat was mated (or the first day you saw mating). You'll get the expected due date, the normal window and a short pregnancy timeline.
How long are cats pregnant?
VCA Animal Hospitals gives a cat's pregnancy (gestation) as 60–67 days, averaging 63–65 days. Because cats ovulate in response to mating, the mating date is a fairly good starting point.
Most likely due date = mating date + 63 to 65 days
Normal window = mating date + 60 to 67 days
Cat pregnancy timeline
| When | What happens |
|---|---|
| About 3–4 weeks | A vet can often confirm pregnancy by feeling the abdomen or with ultrasound. |
| About day 45 | Kitten skeletons show on X-ray, so your vet can count them. |
| Last week | Provide a quiet, warm nesting box and keep her indoors. |
| Last 24 hours | She usually stops eating; temperature may drop below 100°F (37.8°C). |
A kitten is normally born within about 5–30 minutes of active straining, and gaps of 10 minutes to an hour between kittens are common. Call your vet if she strains for longer than that without a kitten, has a fever above 103°F (39.4°C), or loses fresh blood for more than ten minutes.
