You ever notice the glowing eyes of your cat?
I'm lying on the floor in front of my laptop with the tv on but the lights off.
My cat looks over at me and his eyes are glowing green. I think it's funny, and have him follow my hand as I wave at him and see the glowing move around.
I love my cat, and I love to see his glowing eyes.

Actually most nocturnal animals have that reflective surface on the back of their eyes. It allows them to absorb & use more of the available light light & causes that shine. You can actually tell what's watching you by the color of that shine even if you can't make out the creature itself. Wolves ( & their descendants , dogs )for instance have a blue shine while coyotes have a yellow shine.

The eyes, the glowing eyes!! 
The reflective surface acts as an image intensifier so that they can see much better in low light than we can. A cat can see clearly in situations were we would be quite blind. It's pupils can also expand to a larger diameter than ours so that it's eyes can take in as much light as possible. Then what they do take in is amplified by it's inbuilt image intensifier.
A cats brain also uses a sort of motion detector in combination with it's vision. It can't well see something which is perfectly still, but it can instantly detect the slightest motion. A cat's whiskers also act as very sensitive motion detectors so that taking all these things together, a hunting cat can instantly pinpoint the slightest movement made by a mouse.
