Question

Are dogs and cats color-blind? How do they see?

Answer 1

Dogs and cats are color-blind. They see black and white.

Answer 2

yes.

Answer 3

No, neither dogs nor cats are colour blind. Colour blind means an inability to distinguish red from green and since most shades involve these colours to some extent, a colour blind person cannot distinguish many colours well. In truth, dogs and cats can see colours, although not quite to the extent that we can. It's a commonly held myth that dogs and cats see in black-and-white - in fact they don't, and this is not what colour-blind means!

Answer 4

I know dogs are colorblind but I'm not sure about cats.  They see things in greyscale/black and white.  Dark colors to us show up as dark gray or black to them.
