We usually have some appearance of a mouse once every couple of years. I suppose it’s possible others are getting in and being eaten by our cats or dog first, but that seems unlikely. Regardless, I believe cats which have eaten infected meat only shed oocytes for up to three weeks post-infection, and usually don’t shed again, so for most homeowners with indoor cats it’s probably a fairly low risk. I believe gardening and playing around in dirt are both far more likely sources of toxoplasmosis infection anyway.
