Be careful when cleaning a litter box. That’s because cats can shed a parasite called Toxoplasma gondii in their feces. Pregnant woman must be especially careful because if they accidentally inhale or eat the parasite, they risk becoming infected, which means their fetus has a 20% to 50% of also becoming infected.
If a woman is infected within her first trimester, it could lead to microcephaly and other birth defects, as well as an increased risk of mental disability and blindness later in the child’s life. Toxo infection has also been linked to aggressive or suicidal behavior.
