For pregnant women, there is no need to keep a cat, because under the normal condition of keeping a cat, they will not be infected with toxoplasmosis. Infection caused by Toxoplasma gondii virus is usually caused by Toxoplasma gondii virus in feces discharged by cats. Pregnant women will be in direct contact with fecal secretions, and there is just a wound in the contact area of pregnant women, which will cause toxoplasmosis infection. Therefore, as long as pregnant women don't have direct contact with cat feces and close physical contact with cats, it usually has no effect on pregnant women, so it is ok for pregnant women to keep cats.

Toxoplasma gondii mainly exists in trophozoites, cysts or oocysts, and is transmitted through cats' bodies or excreta. Once a pregnant woman is infected, it will be transmitted to the fetus through the placenta. According to statistics, about one third of fetuses will be infected with Toxoplasma gondii, especially early pregnant women, and even lead to abortion. For pregnant women infected with Toxoplasma gondii in the third trimester of pregnancy, it will indirectly lead to fetal brain damage, and abnormal symptoms such as hydrocephalus, microcephaly and umbilical loss will appear after birth.

But that doesn't mean pregnant women can't have cats. Relevant research by CDC in the United States proves that pregnant women can still keep cats as long as they can correctly understand and scientifically prevent Toxoplasma gondii. During the period of raising cats, pregnant women should not change the cat litter themselves, ensure that the cat litter is changed once a day, do not throw it away anywhere, do not feed the cats raw or half-baked food, do not raise new cats, especially kittens, and avoid contact with stray cats, so that cats can still be raised at home.
