It is not recommended for pregnant women to keep pets because pets can be infected with toxoplasmosis or viruses, which can be found in the feces and secretions of pets. If a pregnant woman is infected with Toxoplasma gondii, it may cause developmental disorders in the fetus during the early stages of pregnancy, as well as miscarriage, preterm labor, and even stillbirth. If the fetus is infected with Toxoplasma gondii, it will show enlarged liver and spleen, jaundice and anemia after birth. Infants and young children infected with Toxoplasma gondii may suffer from mental and visual disturbances. If infected with the virus, it can also produce some adverse symptoms. Therefore, it is not recommended for pregnant women to keep pets and have close contact with pets, and close contact with pets should be prohibited during the preparation for pregnancy.
