Ever wondered what your furry friend gets up to when you're at school?

A group of scientists have fitted nine cats with cat cams to see what the moggies get up to when their owners are out.

The mini cameras show the results of what the felines' favourite activities are when left in an empty house.

Check out the cat cam clip to see what they got up to! It's from a report called The Secret Lives of Cats.
