Frequently Asked Questions

How long are cats pregnant?

Cats are pregnant for approximately 63–65 days (about 9 weeks), with a normal range of 58–67 days. This is the feline gestation period. Kittens born before 58 days are unlikely to survive without intensive care. If your cat has not delivered by day 67–68, contact your vet.

How long is the gestation period for cats?

The feline gestation period is 58–67 days, averaging 63–65 days. This is roughly the same as dogs. Unlike dogs, cats can go into heat again within weeks of giving birth, so unspayed cats can become pregnant very frequently.

How long is a cat pregnant in weeks?

A cat is pregnant for approximately 9 weeks (63–65 days). The pregnancy is divided into three trimesters of roughly 3 weeks each. Visible signs such as abdominal swelling typically appear from week 4–5 onward.

How can I tell if my cat is pregnant?

Signs include nipple "pinking up" (rosy, enlarged nipples) around week 3, mild morning sickness, increased appetite, and abdominal swelling from week 5. A vet can confirm pregnancy by ultrasound as early as week 3–4.

What does cat pregnancy look like week by week?

Week 1–2: fertilisation and implantation. Week 3: nipples begin to pink and enlarge. Week 4–5: morning sickness possible, ultrasound can confirm kittens. Week 5–6: abdomen visibly rounds. Week 7–8: kittens gain significant weight, movement may be felt. Week 9: birth typically occurs.

What should I feed my pregnant cat?

From week 4, transition your cat to a high-quality kitten food, which is more calorie-dense. From week 5–6, feed free-choice (ad libitum). Ensure fresh water is always available. Avoid raw food, which can carry pathogens harmful to foetuses.

How many kittens will my cat have?

Average litter size is 4 kittens, but ranges from 1–12. First-time mothers tend to have smaller litters. A vet can estimate litter size by ultrasound at 3–4 weeks or by X-ray after week 7.

What are the signs that my cat is about to give birth?

Signs include restlessness, excessive grooming of the genital area, nesting behaviour, refusal to eat, heavy panting, and uterine contractions. Most queens give birth without complications, but contact your vet if no kittens arrive after 2 hours of active contractions.
