Cats are known for their night vision and their hunting, and the way they see the world is quite different from the way we do. Research has shown where cat and human vision overlap and where they part company. Knowing how your cat sees their surroundings makes a lot of their behaviour easier to understand, and it helps in setting up a home that keeps them interested.

The Night Hunters: Special Design of Cat Eyes

Cat's Eyes Special Design

Cats' eyes are built for hunting. Unlike ours, they have a reflective layer behind the retina called the tapetum lucidum. It works like a mirror, bouncing light back through the retina so the eye gets a second chance at any light it missed first time round. It's what makes a cat's eyes glow in photographs, and it lets cats see in light about six times dimmer than we need.

The trade-off is that cat eyes have fewer cones than ours. Cones are the cells that handle colour and fine detail, so cats don't see the world in the same rich colours we do. Research shows that cats rely mainly on one type of cone, which is most sensitive to yellow-green light, while humans have three types covering red, green and blue.
