I'm 6 weeks pregnant and have an 11 month old cat. He doesn't use a litter tray and comes and goes using a cat flap. Although he usually sleeps inside at night, he tends to go out early (about 6) and then comes back in about 7 and jumps on our bed, sometimes leaving a trail of muddy footprints. I've just realised (foolishly late) that there's a chance that these footprints create a risk of toxoplasmosis. We kept the bedroom door shut last night, and he scratched furiously at the door and wailed plaintively for a full half hour between 6.30 and 7 this morning, until I got up. Can anyone advise me what I should do? I don't want to put the baby at risk, but I'm not sure I can cope with this caterwauling!
