Once the rats get close, the cat eats them and then as humans interact with cats, such as cleaning their litter tray, the parasite can then infect a person.
Prof Aktipis said the parasite “somehow evolved to make a rat get turned on by the smell of cat urine, so it goes up to a cat and snuggles with it, and then it gets eaten which completes the life cycle of the toxoplasma”.
He asked: “If that’s not zombification, then what is?”
Previous research from 2016 discovered road rage and other inexplicable extreme bursts of anger may be caused toxoplasma gondii.
