But perhaps the "most intriguing" possibility is that cat owners are more likely to be infected with the parasite Toxoplasma gondii; studies hint that the protozoan, carried by cats and transmitted in their feces, can cause changes in the brains of the humans it infects:
Infections from the parasite have been associated with self-inflicted violence as well as increased suicide rates in women. It has also been suggested that the inflammatory cytokines released during a T. gondii infection in the brain may be the cause of depression in some patients.
