If you read the latest alarmist headlines, you’ll see plenty of news stories claiming that a cat parasite infects your brain and changes your behavior. Part of that behavior change involves taking more risks and liking cats.
Yet researchers from Duke University found that “on the whole, there was little evidence that T. gondii (the cat parasite) was related to increased risk of psychiatric disorder, poor impulse control, personality aberrations, or neurocognitive impairment.”
In other words, there’s little danger that a parasite can affect your behavior. Now there’s no telling how your behavior might change once you start petting a cute kitten and take one home with you.
