Aww, What a Cute Kitty

There's a cat parasite that apparently can cause strange personality changes in people.

Now we know the real difference between cat people and dog people.

What would happen if we isolated a handful of people - a couple thousand maybe - on some random planet, overran it with cats, and came back in a few centuries? I wonder whether it would be similar to what happened on Path in Card's Xenocide.

Not that I'm advocating doing so. Just a thought.
