That's interesting....and interesting, too, the pains Nickolay took to ensure accuracy in regard to cat's vision.

That is very interesting! But how can we know how cats see? (I didnt understand from the article)
-
It wasn't made very clear in the article, KE. But the retina has rods and cones (light receptotors). Rods are for black and white/night vision, and cones are for color (like A Hard Day's Night and Help!*).
When they dissect an eye and look at a slide of the retina under a microscope, there are more rods than there are cones in a cat's eye, so the cat doesn't see colors well, but sees well in the dark, but in B&W with just a hint of color. The shape of the retina (think of it as a projection screen in a movie theater) and the concentration of these light receptors in different parts of the retina determine the field of vision and focus.
