What colors do cats see

Cats see color in a very different way than humans do. Cats see the world in black and white. We do not.

How do cats see?

For cats, color is the result of light passing through a prism. The light reflects off the colored glass or plastic that is placed in front of their eyes. These colored filters bend, or refract, the light, and the cat sees only a spectrum, or rainbow of colors.

What is the difference between infrared and red light?

Infrared light (IR) is the same type of light that humans see as heat. This light is invisible to humans, but it is important to cats. There are two types of IR light: visible to the human eye and invisible to the human eye. Visible to the human eye, infrared light is a form of light that humans cannot see. Invisible to the human eye, the other form of IR is known as red light. The wavelength of red light is slightly longer than visible red light. Cats can see red light, but they cannot see infrared.

What does the different color of a cat's eyes mean?

Cats have two types of color-sensitive cones in their eyes: blue and yellow. A cat's blue cone is more sensitive to blue light, and a cat's yellow cone is more sensitive to yellow light. What this means is that a cat can see a wider range of colors. Blue cones detect blue light, so a cat's blue cones are better at detecting blue light, and yellow cones are better at detecting yellow light.

How do cats see infrared light?

Cats see infrared light the same way humans do: when the light passes through a prism. Cats do not see black and white.

Can cats see ultraviolet light?

Yes. Cats can see ultraviolet light, or UV light. While ultraviolet light is invisible to humans, it is important to cats. Cats can see UV light in a very different way than humans can.

Can cats see polarized light?

Cats see polarized light, or polarized light, the same way humans do. Polarized light has a pattern of dark and light areas. Cats have a third type of light-sensitive cone, called a UV cone. They cannot see the pattern of polarized light on a page, but they can see the pattern of UV light.

But that’s not quite the full story. There is a lot more going on with the cat’s purr than you might reasonably expect. Even the ‘how’ was long a subject of debate. Some thought it was linked to blood flowing to the inferior vena cava, a vein that carries deoxygenated blood to the right side of the heart. Read more

Cat eye color is influenced by two primary factors: iris pigmentation and blue refraction. The iris is divided into two layers, each of which contains pigment-producing cells (melanocytes). The size, spacing, and density of the fibers in the stroma influence how light is reflected and refracted, resulting in the shade of blue. The translucent structures in cats' eyes, like glass, are transparent blue, ranging from nearly colorless to darker blues to violet-hued blues. Read more

4. Cats are mid-sighted. Moggies lack the muscles needed to change the shape of their eyes, which means they struggle to focus on objects that are close to them. Therefore, if you place a toy right in front of your cat’s nose, they won’t be able to see it clearly and will instead use their sensitive whiskers to detect it. Read more
