Cat's carry Toxoplasma Gondii

It's a parasite that can sit dormant or when active will effect the brain in the form of schizophrenia, Alzheimer's, and Bi-Polar disorder.

Although Toxoplasma gondii, the protozoan parasite that causes toxoplasmosis, was identified in 1908, it took more than half a century to identify felines as its primary host. By 1959 it was alleged that “dogs and cats have been most frequently suspected”1 but it was the work of William Hutchinson in the 1960s that convincingly demonstrated the importance of oocysts shed in cat feces in the transmission of T. gondii2-3 This was followed in 1969 by Gordon Wallace’s report showing an absence of T. gondii on remote Pacific islands where there were no cats.4 Therefore, in 1971, the United States Public Health Service recommended that pregnant women should avoid contact with cat feces to avoid becoming infected. T. gondii can be acquired by humans in several different ways. It may be transmitted as a tissue cyst, usually by eating undercooked meat from an infected animal, or as an oocyst.
