Cats love to chase anything, it's in their instinct. If you start wiggling the light of a laser pointer on the wall, expect kitty to come charging, in full "hunt" mode. My cat, Pierre, is sensitive to shadows and light. He watches anything moving on the wall with total interest. He will jump and dance against the walls for hours trying to get that laser light, if allowed to. Make sure not to shine the laser light in your cat's eyes, though, because it can hurt him. Just shine it on the wall and watch the cat ..
