Laser-Guided Cat

As you know (at least, from Half-Life), there are guided munitions that try to hit a target painted with a laser dot. As you may know (at least, from funny cat pictures), there are cats who try to act like they work this way, too. Or just mistake laser dots for fireflies - the result is exactly the same.

Web Animation

 * In V2E6 of RWBY, Yang uses a laser pointer to get Blake to come to her as part of an intervention over her obsession with Roman Torchwick and the White Fang.

Web Comics

 * Evil Inc. had a shapeshifting hero trapped this way.
 * The GaMERCaT once ran into a smart turret.
 * Girl Genius had Agatha using flashlight and glasses to the same effect on a Fun-Sized Mobile Agony And Death Dispenser.
 * Head Trip discussed a possible problem Catwoman may encounter during the burglary. If she really was this catty, that is.
