Frequently Asked Questions
- How long is a cat pregnant?
- Cat gestation averages 65 days (range 63–67 days). Queens (female cats) can be harder to track than dogs since they are induced ovulators — mating triggers ovulation.
- How can I tell if my cat is pregnant?
- Signs include 'pinking up' of the nipples at ~day 18, slight weight gain, increased appetite, and nesting behavior. A vet ultrasound at day 21 can confirm pregnancy.
- What should I feed a pregnant cat?
- Switch to a high-quality kitten food from week 3 onwards — it provides the extra protein, fat, and calcium needed. Feed free-choice as the queen's appetite naturally increases.
