Cat pregnancy can be seen 20 days after successful breeding. After 20 days of successful pregnancy, the cat’s nipples will gradually turn pink and become larger, and the hair around the nipples will gradually fall off. After three weeks of pregnancy, the breeder can slowly turn the cat over and carefully observe the cat’s nipples. As time goes by, the cat's abdominal circumference will increase, the breasts will enlarge, and the nipples will turn pink. These cannot definitely indicate that the cat is pregnant, because pseudopregnancy can also cause the above conditions. Only a B-ultrasound can be done. Checking the fetal heart rate will determine whether there are viable kittens or whether the pregnancy was successful.

Symptoms of cat pregnancy:

1. The cat will stop estrus within three days after successful mating. If mating is not successful, the cat will still have estrus symptoms.

2. In the first ten days after the cat is successfully pregnant, the cat does not like to eat in the morning. This situation usually only lasts for 48 hours. Pregnant cats may vomit slightly several times during this period. If a cat is seen doing this after mating, the breeder should pay attention and continue to carefully observe any changes in the cat's behavior and living habits.

3. After a cat is successfully pregnant, the nipples will gradually turn pink and become larger, and the hair around the nipples will gradually fall off.

4. Within a period of time after the cat is pregnant, the cat’s appetite gradually gets better and its food intake begins to gradually increase. 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 keepers.

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