Hi, I'm Lindsay and I'm Marshall. Welcome to Tumble, the show where we explore spooky stories

of science discovery. It's Halloween, which means that we're getting into some scary

seasonal science. Ooh, alliteration. This year we're talking cats and mind control. Mind

control cats. Sounds like a plot for a horror movie.

Exactly, which is why we're making our own scary movie that's based on the very real science

of a very common cat parasite.

Okay, so I see here we have the pages for our script for this movie you wrote.

Yes, it's a scary podcast movie, actually a scary podcast movie trailer.

Ooh, wait, it's just the trailer. Yeah, we're just wetting the appetites for more.

We'll see. So what's my character's motivation and am I going to go into a closet at the end

of a dark hallway because you know you shouldn't open that door.

Marshall, what I want you to do is just channel all of your feelings about cats being evil.

Oh, evil cats. All right, I can see that.

In a world where cats roam among us for better.

I love you, my baby.

And for worse, we love him.

He got you fresh water.

There are lots of threat. So small, so devise.

It is making mice lose their minds.

It's toxoplasma, Gondii, a parasite determined to infect its way to a world domination.

Sending out regions of new microscopic parasites, one getting hitter box at a time.

Until all mice lose their fear of cats.
