You can say poop is poop no matter where it comes from, but it is cat poop that you really have to be concerned with when you are pregnant. Outdoor cats have a tendency to eat more wild animals....catch a parasite which causes "toxoplasmosis". It is passed on by their poop easier because of where they poop...litter boxes or your garden....or your kid's sandbox. They bury it with their feet and track around with it on them. Can you tell I don't like cats?
If you were infected you could have a high fever, swollen lymph system, vision disturbances....
I would say you are safe unless your little dog has had some road kill lately??
Good luck and congrats on your pregnancy!!!
