In humans this parasite has other effects, and it even has different effects on women than men
Infected women, on average, tend to be more outgoing and warmhearted than controls, while infected men tend to be more jealous and suspicious.
So further proof that cats are the biggest risk to our status as dominant species on the planet. They have learned that if you can make the woman happy, the mans opinion gets overridden. Evil, truely Evil. :-)
