Scientists claim they have found new evidence of a link between infection with the protozoan parasite, Toxoplasma gondii, and schizophrenia, in what is described as the largest study of its kind. From a report:The alarming thing is that this parasite has been proven to affect rat behavior, and probably affects human behavior also, without the infected person realizing it.
T. gondii, a brain-dwelling parasite estimated to be hosted by at least 2 billion people around the world, doesn't create symptoms in most people who become infected -- but acute cases of toxoplasmosis can be dangerous. Healthy adults are generally thought to not be at risk from T. gondii infections, but children or people with suppressed immune systems can develop severe flu-like symptoms, in addition to blurred vision and brain inflammation.
In short, it allows cats to enslave humans to support their needs.
There is no cure, or practical solution except to eradicate all the house cats. If you have a pet cat, you may already be a zombie.
