Making cats do un-natural things

I learned today that you can use a flashlight beam to get a cat to run over a dog.

See, I was playing with The Instigator and Goliath (think almost Great Dane sized Dalmation-looking-thing) was lying down at his food bowl.

So, I was letting the cat chase the light and not look where he was going and looking at Goliath chowing down without a care in the world- and I wondered what would happen if I ran the light right across him?

Both of them got a WTF? moment at the same time.
