cats can only spread toxoplasmosis in their feces for a few weeks after they are first infected with the parasite. like humans cats rarely have symptoms when first infected so most people don't know if their cat has been exposed to it. in fact most infected cats appear healthy. there are no good tests available to determine if your cat is passing toxoplasmosis in its feces.
once infected with toxoplasmosis is my cat always able to spread the infection to me?
