Cats and dogs often watch TV with their owners. However, animals have a very different perception of the TV and the screen. 

Dogs, for example, see dichromatically, which means they do not know the green color and its shades. In addition, they perceive blue and yellow tones differently. In addition, for dogs, the picture remains a little vague. 

Cats perceive the world on a monochrome scale, but better distinguish images on the TV. As a rule, they see other animals perfectly there and some even try to catch them when they move on the screen.
