Okay can someone please help me settle something.. So my cousin is about 6 weeks pregnant and she was calling me freaking out because she was around her cats litter box when they went pee and they moved the litter around, (boxes have lids) now she thinks this is going to harm the baby or make her have a miscarriage... is this true? Wouldn't she actually have to change the litter and be right there for it to affect anything??
