Pregnancy is generally recommended to avoid keeping cats, but it is not absolute, such as feeding cats must pay attention to daily hygiene and protection. Toxoplasma gondii is a parasite in cats, and it is mainly found in cat feces. Pregnant women may be infected with toxoplasma gondii through contact with cat feces or contaminated food by cats. If a pregnant woman is infected with Toxoplasma gondii, the healthy development of the fetus will be jeopardized. Toxoplasma can enter the amniotic fluid or the fetus through the placenta, thus causing congenital developmental abnormalities and malformations. Toxoplasma infections in early pregnancy can easily cause miscarriage, and infections in late pregnancy can lead to preterm labor or stillbirth, which is more harmful to the fetus. It is generally recommended that pregnant women should not feed pets as much as possible. If they especially like to feed cats or have been feeding cats, they should pay attention to avoiding contact with cat feces, reduce contact with pets, wash their hands diligently after contact and undergo a toxoplasmosis test during pregnancy.
