Women who carry a common parasite may be more likely to harm themselves or attempt suicide, according to new research. Researchers say more research is needed "to really understand the link between toxoplasmosis and suicidal tendencies, such as whether certain individuals with the infection are more susceptible to mood and behavior issues than others – because of genetic factors, for example."
The researchers added that pregnant women should not avoid or give away their housecats based on the findings. Most of the parasites that cause infection, Weiss said, are passed by feral cats and end up in the environment.
“This is not a reason to be fearful of pussy cats,” he said.
