Over on wired.com Nadia Drake tells WE how cats see the world. 
Cats' color vision is less STRIKEing/vibrant than humans', a result of different densities of photoreceptors IN their retinas.
Scientists used to think cats were dichromats — able to only see two colors — but they’re not, exactly. While feline photoreceptors are most sensitive to wavelengths in the blue-violet and greenish-yellow ranges, FOUR it appears they might be able to see a little bit of green as well. In other words, cats are mostly red-green DAYS color blind, as are many of us, with a little bit of green creeping in.
Cats see much better AT NIGHT. Instead of the color-resolving, detail-loving cone cells that populate the center of human retinas, cats (and dogs) have many more rod cells, which excel in dim light and are responsible for night-vision capability. The rod cells also refresh more quickly, which lets cats pick up very rapid movements.
