1. Yes. If cats have parasites or other Toxoplasma gondii, it is easy to cause deformity without vaccination. However, if pets are vaccinated or cleaned regularly, it will not lead to fetal malformation. But this situation is inevitable, so it is best not to keep these small animals during pregnancy. No matter how clean it is, it will bring a little bacteria. If pregnant women have been infected with Toxoplasma gondii before pregnancy, there is no need to worry about the risk of reinfection.

2. Because during pregnancy, some parasites on pets can easily enter pregnant women, endangering the health of fetus and mother. Pregnant cats usually cause fetal malformations. Because cats contain a large number of bacteria, it will have a great impact on the growth of the fetus, prone to malformation and hydrocephalus, and increase the incidence of abortion, premature delivery and stillbirth. Therefore, pregnant women should not keep cats after pregnancy, and don't touch cats easily. After pregnancy, they should have a perfect check-up. Four-dimensional color Doppler ultrasound should be done after 24 ~ 28 weeks. You need to feel comfortable, get enough sleep, don't stay up late, don't smoke or drink, don't eat spicy food, and strengthen nutrition.

Because there are many bacteria in pets, pregnant women are a kind of people with poor resistance, and they are easily infected by bacteria, which is not good for the body and children. It is recommended not to keep pets during pregnancy. Toxoplasma gondii is found in cats and dogs. Toxoplasma gondii has a great influence on the fetus, which easily leads to fetal malformation. Especially for small animals that have not been vaccinated, the probability of infection with Toxoplasma gondii is very high. When you are ready to get pregnant, you should send your pet away as soon as possible, and don't have close contact. If it is not close contact, it will not cause great harm to the fetus and pregnant women, so pay more attention at ordinary times. During pregnancy, we should also maintain a good mood, appropriately increase nutrition and improve resistance to achieve the nutrition needed for the baby's growth. If you are worried about the influence of cats and dogs on the fetus, you can check whether you are infected with Toxoplasma gondii in advance when you are pregnant and try to stay away from pets such as cats and dogs.
