Today we're talking about one of the last mysteries of science.
No, not if the universe will keep expanding forever, but this.
How did cats and dogs find their way home over long distances?
Hmm, we hear incredible stories of lost pets,
travelling tens and even hundreds of miles home.
But scientists struggle to explain how they do it.
We'll hear the view of one scientist today,

Neil, are you a cat person or a dog person?
Oh, that's easy.
I'm a cat person for sure.
Dogs are just, uh, well they're hard work aren't they?
If you say you're a cat person, it means you prefer cats.
A coffee person prefers coffee.
A something person likes or prefers that thing,
often over another thing.
