How to tell if your cat is pregnant
The first visible sign is usually “pinking up”: around three weeks after mating her nipples become pinker and larger. Her belly then rounds out from about five weeks, and her appetite increases. A vet can confirm pregnancy by feeling her abdomen or by ultrasound.
