The most interesting thing about cat woman disease is what Sapolsky mentioned: what else is out there that we are not aware of?
Obviously Howard Bloom has already dealt with this issue on another plane. The Super-organism plane.
But what about a spiritual parasite? Can there be the same as a spiritual equivalent of toxo? (toxoplasmosis).
What I suggest is to stop hanging out with insane people because until the spiritual equivalent of toxo is discovered you might as well be careful. After all we see the effects of hanging out with insane people. There is no question that it is infectious. So far we do not know how it is infectious but we know it is. As the Rambam wrote "a man is drawn in his opinions the the people he hangs out with."
