The probability of raising a cat during pregnancy is unlikely to have any impact on the fetus. Most people worry that Toxoplasma gondii from cats can be transmitted to pregnant women. However, research has found that only cats infected with Toxoplasma gondii for the first time shed the eggs in their feces during the first two weeks of infection. Moreover, Toxoplasma gondii oocysts in cat feces need to "incubate" in the external environment for a day before they become infectious. Based on this calculation, the probability of an expectant mother raising a dangerous cat is very small. If the cat owner is pregnant, there is no need to worry too much about the impact of the cat on the fetus. Just do a good job of cleaning and cut off the transmission path.

Precautions for pregnant women raising cats:

1. Pay attention to cat hygiene when raising cats during pregnancy. Ask family members or pet shop staff to bathe the cat regularly and clean it in time. Cat feces should be disinfected and sterilized regularly, and hands should be washed promptly and carefully after contact with animal excrement.

2. If you have excessive contact with cats during pregnancy, you should be aware that cats can easily scratch pregnant women under certain special circumstances, and may also cause emotional stimulation to pregnant women, which is not conducive to normal pregnancy.

3. During pregnancy and preparation for pregnancy, it is generally not recommended to have contact with cats and dogs, nor to keep other pets. All animals will have bacteria and viruses. If you are interested in raising pets, it is recommended to do it after the lactation period.
