IIRC toxoplasmosis affects the brains of rodents making them less afraid of cats, which means that they're more likely to be killed and eaten by those cats, which spreads the infection to the cats. I think there have been claims that perhaps it also makes infected people like cats more in a similar fashion, which I guess is what GP is referring to.
