Usually Yes... People and animals that see in color have specialized cone cells. They also have something called a tepetum negre-It's a black layer of skin on the back of the eye that absorbs different colors of light. Animals that lack these cone cells, such as owls and other nocturnal animals see in black and white or just shades of green or blue- it depends on how many cone cells cells they have and what they do. nocturnal animals have the same piece of skin on the back of the eye but it's called a tepetum and is reflective (almost silverish in color, like a mirror). Instead of having the rays of light absorb into the back of the eye, waves of light are reflected off the tapetum and bounce back out of the eye - increasing the amount of light surrounding the eye-

so the animal can see better in the dark. This is why owl or cat eyes seem to glow at night. It's also the reason that your cat's eyes look like lighbulbs in a photograph-it's the light of the flash reflecting off the tepetum and out the eye.
