    If it made us like cats more there would be a higher chance of cats becoming more prevalent, which would be good for the parasite yes? So there could be some evolutionary pressure there. Not that I’m saying it has actually happened, but theoretically it might be advantageous.

      evolutionary pressure happens over generations and via sexual reproduction, as far as i’m aware. humans are a biological dead-end for toxoplasma, there’s no way for t gondii to “learn” that there’d be any benefit to changing human behaviour, let alone how to do so.
