- A cat is usually pregnant about nine weeks, or just over two months. Most cats give birth about 63 to 65 days after conception.
- During the early weeks, a cat's nipples will swell and turn pink. She may also experience morning sickness.
- During the middle stages of a cat's pregnancy, at about five weeks, her belly will start to swell. She should be kept in a low-stress environment and be fed high-quality cat food.
- A few days before your cat's pregnancy comes to term, she may seek out a private place to give birth, a process called "nesting." At this time, her nipples will probably start to produce milk.
- Nervousness and panting are common signs that the cat is having contractions. Birthing multiple kittens can take as little as a couple of hours or up to half a day or more in some breeds, and pauses between kittens are not uncommon.
