FAQs
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.
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.
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.
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.
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.
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.
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.
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.
