Cat Gestation Period: How Long Is a Cat Pregnant?

Last updated

A cat is pregnant for about 64 days, roughly 2 months. Normal queening happens between 61 and 67 days, and a typical litter is 3-5 kittens.

How long is a cat pregnant?

A cat carries her kitten for an average of 64 days, or about 2 months. Counting from the breeding date, queening is normal anywhere from day 61 to day 67.

Cat gestation stages, month by month

Days 1–21: fertilisation and implantation

Ovulation follows mating and embryos implant around days 12 to 14. Nipples turn pink and enlarge from about day 18, which is often the first visible sign.

Days 22–42: foetal development

Ultrasound confirms pregnancy from about day 21. Appetite rises steadily. Switch to kitten food so energy and calcium intake keep pace with foetal growth.

Days 43–56: growth phase

The abdomen is clearly rounded and kitten movement can be felt. Set up a quiet, warm nesting box in a low-traffic room and let her get used to it.

Days 57–64: pre-queening

Appetite may drop in the last day or two. The queen becomes restless, seeks the nest and may vocalise. Keep her indoors and monitor daily.

Week 1

What's happening: Mating triggers ovulation and fertilisation follows within about two days.

What to do: Keep the queen indoors and record the mating dates.

Week 2

What's happening: Embryos travel to the uterus; implantation begins around day 12 to 14.

What to do: No change to feeding. Avoid flea and worm treatments not licensed for pregnancy.

Week 3

What's happening: Nipples pinken and enlarge, the classic early sign.

What to do: Book an ultrasound. Continue normal, good-quality food.

Week 4

What's happening: Ultrasound shows heartbeats; some queens have brief morning sickness.

What to do: Offer smaller, more frequent meals and start transitioning to kitten food.

Week 5

What's happening: Foetuses gain weight rapidly and the abdomen rounds out.

What to do: Feed kitten food free-choice or in several meals a day.

Week 6

What's happening: Movement may be visible; appetite is at its highest.

What to do: Keep her indoors. Prepare the nesting box in a quiet room.

Week 7

What's happening: Kittens are fully formed and the queen slows down.

What to do: Show her the nesting box and keep the household calm.

Week 8

What's happening: Milk may be present; nesting behaviour intensifies.

What to do: Have towels, a heat source and the vet's number ready.

Week 9

What's happening: Appetite drops, restlessness increases and labour begins.

What to do: Monitor daily and stay nearby but avoid interfering unless there is a problem.

Signs a cat is pregnant

  • Nipples pinkening and enlarging from about day 18
  • No return to heat after mating
  • Brief appetite loss or vomiting in weeks three and four
  • Ultrasound confirmation from about day 21

Signs of approaching queening

  • Steady weight gain and a rounded abdomen from week five
  • Nesting, restlessness, vocalising and refusing food in the final 24 hours
  • Contact your vet if labour stalls, if the animal strains without progress, or if there is abnormal discharge before queening begins.

What affects cat gestation length

  • Cats are induced ovulators: ovulation is triggered by mating, usually 24 to 50 hours afterwards, so the mating date is a closer anchor than in dogs but still not exact.
  • A single litter can have more than one father if the queen mates with several toms during the same heat.
  • Queens can come back into heat while still nursing, sometimes within a few weeks of giving birth.
  • Around day 35 the abdomen enlarges noticeably, a change breeders often call pinking-up when it follows the nipple colour change at about day 18.

Cat pregnancy FAQs

How long is a cat pregnant?

About 64 days, roughly nine weeks. Normal queening happens anywhere from 61 to 67 days after mating, so treat the calculated date as the middle of a week-long window.

Is the mating date reliable for cats?

More reliable than in dogs, because mating induces ovulation within 24 to 50 hours. It is still an estimate, especially when the queen mated repeatedly over several days.

Can kittens in one litter have different fathers?

Yes. A queen may mate with several toms during one heat and ovulate multiple eggs, so kittens in the same litter can have different sires.

When can a vet confirm pregnancy?

Ultrasound detects pregnancy from about day 21 and X-ray gives a kitten count from about day 45, once the skeletons have mineralised.

What should I feed a pregnant cat?

Switch to a kitten or all-life-stages diet from around week four and let her eat frequent small meals. Energy needs rise by roughly 25 to 50 percent by late pregnancy.

When should I call the vet during queening?

If she strains hard for more than 30 minutes without producing a kitten, more than two hours pass between kittens, there is heavy bleeding or foul discharge, or she seems exhausted or distressed.
