Are cats color blind

Cats are protanopic. There is a type of cell in the eye called "rod cells" whose main function is to distinguish colors. Human rod cells can distinguish blue, red, and green colors, but cats do not have rod cells that can detect red, so they can only distinguish blue and green, but not red. Therefore, when cats see red objects May turn gray.

Although cats can distinguish blue and green, there are certain barriers between the eyes and the brain's perception, making it impossible for the brain to interpret this information. So whether cats can distinguish colors doesn't mean much to them.
