Is Your Kitty Colourblind?
Cats are renowned for their night vision but can they see colour in the same way we do? Well, they aren’t colourblind but they can’t distinguish colours very well.
Scientists believe that cats see the world in shades of yellow and blue in much the same way that humans who are red-green colourblind see their environment. Colour vision enables us to identify stationary objects against a backdrop and it is the humble bumble bee that has a far superior colour vision, detecting flowers from a vast distance relatively speaking.
Our feline friend’s vision has evolved differently. Cats are predators and have perfected the art of the ambush attack. They can sit like a statue and target in on moving prey. This is why your cat will immediately respond by pouncing if you move his or her toy. However if you leave it stationary they may not react.
Cat’s eyes are positioned at the front of the head which means that they have similar binocular type vision to humans. This is what makes the cat so good at judging distance.
As cats are nocturnal hunters colour vision isn’t as important to them. They can’t see in complete darkness but can see better than most other animals in semi-darkness. This makes the cat sensitive to light and you will notice how their pupils contract into narrow slits in bright daylight. In darkness the pupils expand to allow the maximum amount of light in. Cat’s eyes also reflect in the darkness. This happens when light hits the yellow or green crystalline needles that line their eye.
