Signs of blue cat pregnancy:

1. Increased appetite. During a period of time after the cat is pregnant, the cat's appetite gradually improves and its food intake begins to gradually increase.

2. The nipples turn pink and the surrounding hair will fall out. After three weeks of pregnancy, the breeder can slowly turn the cat over and carefully observe the cat’s nipples. Because after a cat is successfully pregnant, the nipples will gradually turn pink and become larger, and the hair around the nipples will gradually fade away.

3. About 1 month into pregnancy, the abdominal circumference begins to increase. The fetal movement can be felt on the abdominal wall, and the fetal heartbeat can be heard with a stethoscope.

4. Some changes in personality: The personality of a pregnant cat may become gentle or rough.

5. Cats in daily life prefer to lie still and do not want to move, and they do not want to play with their owners or breeders.
