Can dogs and cats see colors?
Dogs and cats have rods and cones in their retinas but in a different proportion than in the human retina. Although they can differentiate colors, what they see is likely a more muted version of what we see. Dogs, especially, probably see more shades of gray than they do all of the individual colors.
Cats, by the way, can concentrate small amounts of light in their eyes, which allows them to see at night when the rest of us have difficulty. This special talent gives them their extraordinary night hunting vision.
