Toxoplasmosis: Behavioral changes
http://en.wikipedia.org/wiki/Toxopla...vioral_changes
It has been found that Toxoplasma gondii parasite is capable of changing the brains of whatever organism it infests. In mice, they lose the fear of cats and are even attracted to cat-urine. Making the asexual portion of the Toxoplasma gondii life-cycle faster to complete in order to replicate more quickly into its sexual reproduction phase in all host cats. This loss of fear and apprehension manifesting itself in humans in a similar manner, even when common-sense tells them they should depend on that sense of fear or doubt for their own survival.
Here are other ways that this parasite have been known to alter the thinking patterns of humans:

I strongly suspect that it might even be responsible for all cat-lovers' wholly contradictory behavior of putting cats, all other animals, and even all humans in harm's-way through their adamant insistence of promoting TNR programs, just to ensure the survival and spread of more Toxoplasma gondii parasites throughout the food-chain and in more humans. They are, in effect, being controlled against all reason and common-sense by the very parasite that is reproducing in their cats.
The stuff that sci-fi used to be made of come to reality. Real-life "pod-people". They can't think nor reason beyond the need of ensuring the survival and proliferation of Toxoplasma gondii. It won't let them.
Get tested for T. gondii if you are defending cats' lives. You're actually obeying parasites in your brain. You no longer think and reason like a human, ignoring all common-sense.
