So... let me get this straight... anybody that disagrees with you is obviously being controlled by a parasite?? You've been watching too many late night sci-fi movies! The parasitic brain-snatchers have taken over!
I agree with Critter - YOU are the one exhibiting paranoia. Remember there are many more ways than cats to get infected! You said yourself you're breeding mice - mice can carry the parasite too. Without testing those field mice, you don't know if they've been exposed or not.
