Frequently Asked Questions
How long is a cat’s gestation period?
The average feline gestation period is 65 days (around 9 weeks), with healthy normal births occurring between days 63 and 67.
What are the early signs of cat pregnancy?
Around week 3, the nipples become enlarged and turn rosy pink ("pinking-up"). From week 4 onwards, abdominal swelling develops and ultrasound confirms fetal viability.
What should a pregnant cat be fed?
Starting around weeks 4-5, transition the queen to high-protein, calorie-dense kitten food to support fetal development and upcoming lactation.
How Long Are Cats Pregnant?
The average gestation period for cats is about 9 weeks, or approximately 2 months. In days, this typically ranges between 63 and 67 days. However, pregnancies lasting from 58 to 72 days can also be considered normal. If your cat has passed 72 days without giving birth, you should consult your veterinarian immediately.
Cat Pregnancy Stages Week by Week
Your cat's pregnancy can be divided into three main eras (trimesters):
- Weeks 1-3: First signs appear. Nipples become pink ("pinking up"), and slight weight gain may occur.
- Weeks 4-6: The abdomen becomes noticeably larger, and appetite increases. Kittens' heartbeats can be heard during a vet check-up.
- Weeks 7-9: Preparations for birth begin. The mother cat starts nesting, moves more slowly, and milk may leak from her nipples.
