What Do They See

Many people wonder how animals view the world around them. Is it in shades of grey, or do they see the vibrant colours that our eyes can detect? Plenty of evidence now suggests that cats and dogs do see in colour, but without the vividness and wide colour spectrum available to the human eye. Animals live in a more pastel world.

The reason for this difference lies at the back of the eye, an area called the retina. Here special cells, known as rods and cones, are found. The sensitivity and ratio of these cells is different in animals when compared to humans, resulting in highly efficient vision in dim lighting with a narrower colour range. Dogs see mainly yellow and blue hues and can differentiate between shades of grey so subtle that they would appear as one colour to us. Cats see some colours but their speciality is vision in low light, where their eye is up to 130 times more efficient than ours. Both dogs and cats have difficulty seeing close objects but their sense of smell and taste more than compensate.
