But despite their popularity, scientists know surprisingly little about their behavior once they've left the cat flap.

Got a fairly wide range of types of housing and, hopefully, types of cat here.

Yeah, definitely.

The built-up area, if I'm looking at the map, seems to be behind us.

And then these houses in front of us here look to back all onto fields.

They want to find out more about how far cats travel each day.

So hopefully we'll get cats roaming out of their back gardens and up into the farms.

How these solitary creatures manage to live side by side...

I'll expect some of these houses in this more built-up area, there might be multi-cat households.

And where cats really find their food.
