food and laps, that is all they see.
just kidding, i cant quote a source right now, but i do remember a great show on scientist who study cats eyesight and reproduced for you a cats eyesight, they showed what the cat would see.
it was washed, no detail, i think it was black and white, or it may have been little difference in color, like different shades of the same color.
they dont see detail, like we do. if you are laying in the grass, they cant see the difference between you and the grass, like if you see a person in a dark alley, you see a shape, but you cant tell who it is.
they judge by movement, if you were laying on the grass and moved, they would see the big difference between you and the grass. you would move and the grass would not.
cats recognize us more by hearing and smell.
