This ability is due to the structure of the cat's eye. For the size of his head, a cat has extremely large eyes.
Rods are responsible for magnifying light impulses.
The cat has an increased number of rods. Cats also have a highly developed reflective area in the back of their eyes called the tapetum lucidum. A number of animals, such as deer and raccoons also have this tapetum lucidum. Inc. All rights reserved.
