Pregnant women are not recommended to keep cats, and if they must keep cats, it is recommended to deworm them and stay away from cat litter. Cats are hosts of Toxoplasma gondii. Pregnant women who come into contact with cats infected with Toxoplasma gondii may be indirectly infected with Toxoplasma gondii, which may affect the growth and development of the fetus, and may even lead to growth and developmental deformities, and miscarriages and preterm deliveries, so it is not recommended to keep cats during pregnancy, or to keep any other pets. Toxoplasma gondii infected cats have Toxoplasma gondii cysts in their feces. After infection, cats excrete cysts in their feces, and the cysts are infectious after developing in the outside world for 1-2 days or more. If you must keep a cat during pregnancy, pregnant women need to stay away from cat litter and cat feces, while family members need to remove cat litter or cat feces daily.
