Cat pregnancy (gestation) typically lasts between 63 and 67 days, with the average being 65 days — approximately 9 weeks. Some breeds, like Siamese cats, may have slightly longer gestation periods of up to 70 days. The pregnancy is counted from the day of mating. If you know the mating date, you can estimate the due date by adding 65 days.

Early signs of cat pregnancy include: "pinking up" (nipples becoming pinker and more prominent) around week 3, increased appetite, possible morning sickness (vomiting) around week 3-4, increased affection or clinginess, and gradual weight gain. A veterinarian can confirm pregnancy via ultrasound as early as day 18-21 or via abdominal palpation around day 20-30.

Fetal movement can typically be felt by a veterinarian through gentle abdominal palpation around week 5 (days 29-35). For pet owners, visible or palpable movement may become noticeable around week 6-7 when the kittens are larger and more active. You might see the queen's belly ripple or twitch as the kittens move.

Pregnant cats need high-quality, nutrient-dense food. Switch to kitten formula food (wet or dry) starting around week 3-4, as it contains higher protein, fat, and essential nutrients like DHA for fetal brain development. Feed small, frequent meals as the growing uterus takes up abdominal space. Always provide fresh, clean water. Avoid raw diets during pregnancy due to infection risk. Consult your vet about any necessary supplements.

Set up a nesting box (queening box) by week 7-8 in a quiet, warm, draft-free area. Use a large cardboard box or plastic tub lined with soft, washable bedding (old towels work great). The box should be large enough for the queen to stretch out but with sides high enough to keep kittens contained. Keep the room temperature around 72-75°F (22-24°C). Have your vet's emergency number handy, and stock supplies like clean towels, a heating pad (set on low, under half the box), and kitten milk replacer just in case.

A typical cat litter consists of 3 to 5 kittens, though litters can range from 1 to as many as 9+ kittens. First-time mothers (queens) tend to have smaller litters. Factors influencing litter size include the cat's breed, age, health, and genetics. An X-ray or ultrasound in the later stages of pregnancy (week 7-8) can help estimate the number of kittens expected, which is useful for knowing when all kittens have been delivered during labor.

Schedule a vet visit around week 3-4 to confirm pregnancy via ultrasound or palpation. A follow-up visit around week 6-7 can check on fetal health and estimate litter size. Discuss deworming protocols with your vet, as roundworms can be passed to kittens through milk. If you notice any concerning signs — such as vaginal discharge, prolonged labor (straining for 30+ minutes without a kitten), fever, or lethargy — contact your vet immediately.

Yes! Similar to humans, pregnant cats can experience morning sickness, typically around week 3 to 4 of pregnancy. You may notice your cat vomiting occasionally or showing a decreased appetite. This is usually due to hormonal changes and the stretching of the uterus. If vomiting is frequent or severe, or if your cat stops eating entirely for more than 24 hours, consult your veterinarian to rule out other issues.

"Pinking up" refers to the noticeable change in a pregnant cat's nipples, which become pinker, more prominent, and slightly swollen around week 3 (days 15-21) of pregnancy. This is one of the earliest visible signs of pregnancy in cats and occurs due to increased blood flow and hormonal changes preparing the mammary glands for eventual nursing. It's most obvious in first-time mothers or cats with lighter-colored nipples.

This tracker provides a general guideline based on a typical 65-day cat pregnancy. Individual cats may vary — gestation can range from 63 to 67 days (or slightly longer for some breeds). The developmental milestones described for each week are based on established veterinary knowledge. For precise medical guidance specific to your cat, always consult your veterinarian. This tool is intended for educational and informational purposes, helping you understand what to expect during each stage of feline pregnancy.
