Not the OP. Toxoplasmosis from what I understand can cause mice to lose fear of cats. So I think what the OP is suggesting is that toxoplasmosis is brain washing us to like cats and without it we would abandon some cats.
I thought it was associated with higher risk taking. The mice are less fearful in general, hence they may take risks that make them more likely to be seen/caught/trapped/eaten by the cat.
There's a story about a doctor (I think) who started to have a sixth sense for ordering toxo tests for people who came in to the ER with motorcycle injuries. The tests often came back positive. IIRC the high positivity was due the fact that toxo increases risky behavior in humans as well as mice.
It's still an open question why mice with toxo don't end up in hospital for motorcycle injuries. I have an inkling that it is correlated with the low rate of human toxo victims eaten by cats each year, but who knows.
