The thing I love about cats is that they're very independent but very loving.

You can play with them.

They're comforting.

They're furry.

If he's out, I get lonely.

When he's in, fine, I'm all right.

Well, you can see how lovely it is to have him near me and be able to stroke him.

We may love our cats, but how much do we really know them?

They have a secret life that remains a mystery.

With leading cat scientists, Horizon has set up an experiment to find out what they get up to.
