Generally, cats can undergo B-ultrasound at about 6 weeks of pregnancy, because at this time, the fetus of the female cat can already be seen in a spherical shape. An experienced pet doctor can also see the status of the fetus through B-ultrasound. If possible, you can also do an X-ray on the cat to check the specific condition of the fetus in the mother cat. In addition, pregnant female cats may have red and swollen breasts and enlarged abdomen. Of course, this is also a suitable time to see a B-ultrasound.

Symptoms of cats before giving birth:

1. The abdomen is obviously sagging. The fetus has been fully developed before delivery, so it is relatively large, which makes the female cat's abdomen significantly expand and become larger, and the two rows of nipples can be seen more clearly.

2. Cats may drink a lot of water during labor. When mucus is found flowing out of the cat’s vulva, it indicates that the cat is about to give birth, and it must be placed in the delivery room in time.

3. Generally, about 12 hours before it gives birth, the cat will show symptoms of restlessness, especially its uterus will continue to contract at this time, and there will be bursts of pain in the abdomen. , the cat looks particularly uncomfortable at this time, and its breathing becomes more rapid.

4. On the day of delivery, female cats generally do not eat. If there is no disease interference, a female cat suddenly stops eating, which is an important sign of childbirth.

5. During the interval between labor pains, the female cat may drink a lot of water.
