When should I call a vet during cat labour?

Contact a vet if: active straining has continued for more than 30–60 minutes without delivery of a kitten; more than two hours pass between kittens when you know more are present; the queen appears in severe distress, is unresponsive, or collapses; a kitten appears partially delivered and cannot be passed; the discharge is foul-smelling; or the queen has been in Stage 1 (restless, nesting) for more than 24 hours without progressing to active delivery. Dystocia (difficult birth) is a veterinary emergency — prompt intervention is critical. Do not attempt manual extraction without veterinary guidance as it can cause severe injury.

Cat Pregnancy Guide: Signs, Stages and Care

Q: How long is a cat's pregnancy?

The average feline gestation period is 63–65 days from conception, with a normal range of 58–70 days. Litters born before day 58 are considered premature and kittens may not survive without intensive care. Litters significantly past day 65 may warrant veterinary assessment as prolonged pregnancy can indicate foetal complications. Because cats are induced ovulators — they ovulate in response to mating rather than on a fixed cycle — the conception date can be difficult to pinpoint exactly, making precise due date calculation challenging. Vet assessment including abdominal palpation or ultrasound can give a more accurate stage of pregnancy estimate.

Q: How do I know if my cat is pregnant?

Early signs of pregnancy in cats include: enlarged, pinkish nipples (nipple pinking occurs from about 2–3 weeks post-conception and is one of the earliest visible signs, particularly in first-time queens); morning sickness and occasional vomiting in the early weeks; gradual abdominal enlargement from around week 4–5; increased appetite from mid-pregnancy; nesting behaviour in the final 1–2 weeks (seeking out quiet, enclosed spaces to prepare for birth); and reduced activity as the pregnancy progresses. Definitive confirmation comes from veterinary examination — abdominal palpation can detect foetuses from around day 20–30, and ultrasound can confirm pregnancy and foetal heartbeats from around day 25.

Q: What should I feed a pregnant cat?

A pregnant cat's nutritional needs increase significantly from around the third week of pregnancy and continue through lactation. Kitten food is the standard recommendation for pregnant and nursing queens — it is higher in protein, fat, calories, calcium, and phosphorus than adult maintenance food, meeting the increased demands of pregnancy and milk production without requiring separate supplementation. Feed the kitten food freely (ad libitum feeding) from the point of confirming pregnancy — restricting calories during pregnancy can compromise foetal development. Do not supplement with additional calcium during pregnancy as excess calcium can paradoxically interfere with calcium metabolism during the critical period around birthing.

Q: What is normal during cat labour?

Labour in cats has three stages. Stage 1 (cervical dilation) lasts 12–24 hours and is not visually obvious — the cat may become restless, seek her nesting area, and breathe more rapidly. Stage 2 (active delivery) involves visible abdominal contractions and delivery of kittens. Each kitten is typically born within 10–60 minutes of active straining beginning; the interval between kittens can range from 10 minutes to an hour. Stage 3 involves passage of the placenta after each kitten. The queen typically licks each kitten immediately to stimulate breathing, removes the amniotic sac, and severs the umbilical cord. The entire delivery of a litter of 4–6 kittens may take 2–6 hours.

Cat pregnancy guide — signs, stages, feeding and when to call the vet

Reviewed by Dr. Ameer Hamza, DVM

Whether you have discovered your cat is pregnant unexpectedly or have a planned breeding, understanding the stages of feline pregnancy and what your cat needs at each stage makes a significant difference to outcomes. Cat pregnancy is relatively short but the changes are significant and the nutritional and environmental needs of a pregnant queen are different from those of a non-pregnant adult. This guide covers every stage from confirmation to kittening and the early postnatal period.

Is Your Cat Pregnant? Early Signs

The earliest visible sign of pregnancy is nipple pinking — the nipples enlarge slightly and turn a more vivid pink or red colour, typically from about 2–3 weeks post-conception. This is particularly obvious in first-time queens who have never nursed kittens. Some cats experience a period of morning sickness in early pregnancy, with occasional vomiting or reduced appetite that resolves by mid-pregnancy. Weight gain and abdominal enlargement become visible from around week 4–5. Definitive confirmation requires veterinary examination: a vet can palpate foetuses from around day 20–30, and ultrasound can confirm pregnancy and foetal heartbeats from around day 25. X-ray confirmation of kitten count (by visualising foetal skeletons) is typically done close to term, around day 45–55.

Weeks 1–3: Early Pregnancy

The first three weeks of pregnancy are not visually obvious. The fertilised eggs implant in the uterine wall and the embryos begin development. You may notice nipple pinking and occasional early morning sickness. Continue normal feeding at this stage. If your cat goes outdoors, consider restricting outdoor access from the point you suspect pregnancy to protect both her and the developing kittens from injury, infection, and stress. Schedule a vet appointment to confirm the pregnancy and establish a health baseline.

Weeks 4–6: Mid-Pregnancy

Visible abdominal enlargement begins. The queen's appetite increases substantially — from around week 4 onwards, transition to free-feeding kitten food to meet her increasing caloric and nutritional demands. Body weight increases steadily through this period. The foetuses are growing rapidly and the queen may be slightly less active than usual. The vet may be able to palpate the kittens at the week 4–5 examination and ultrasound confirms foetal heartbeats. Parasite treatment — if needed — should be discussed with your vet to ensure only products safe for pregnant cats are used.

Weeks 7–9: Late Pregnancy

The abdomen is now visibly large and the queen may have difficulty moving comfortably. She may begin nesting behaviour — searching for quiet, enclosed, secure areas to prepare for birthing. Provide a suitable kittening box: a large cardboard box or commercially available nesting box, lined with clean towels or newspaper, placed in a quiet room away from household traffic. Introduce the queen to the box early so she is familiar with it before labour. Continue free-feeding kitten food. The mammary glands enlarge and may begin producing colostrum (early milk) in the final days before birth. The queen may become more affectionate or, conversely, more reclusive as term approaches.

Labour and Delivery

Normal labour progresses through three stages. Stage 1 involves uterine contractions and cervical dilation that are not externally visible; the queen is restless, seeks her nesting area, may vocalise, and breathes more rapidly — this can last 12–24 hours. Stage 2 is active delivery: you will see visible abdominal straining and kittens are delivered one by one. Each kitten should be born within 10–60 minutes of active straining beginning. The interval between kittens ranges from 10 minutes to about 1 hour. Stage 3 is passage of the placenta after each kitten. Most queens manage delivery without intervention, cleaning each kitten immediately. Provide quiet, calm observation rather than hovering — most queens do not need or want active assistance and excessive interference can cause a stressed queen to neglect her kittens.

Postnatal Care

After delivery, ensure all kittens are nursing and the queen is producing milk. Colostrum (produced in the first 24–48 hours) is essential — it transfers maternal antibodies to the kittens and must be consumed in the first day of life. Weigh kittens daily for the first 2 weeks; healthy kittens gain weight consistently from day 2 onwards. Any kitten failing to gain weight or losing weight needs urgent attention — supplemental feeding or veterinary assessment may be needed. Continue free-feeding the queen with kitten food throughout lactation, as the nutritional demands of nursing are even higher than those of pregnancy. Book a post-kittening vet check within a few days of birth to confirm all kittens are healthy and the queen has recovered well.
