actually cat's eyes start out blue, when they get older they sometimes change to yellow or green. Cat's eyes glow because the light is absorbed and then reflected back, making them seem green.
Foxes have a tapetum in the back of their eyes that reflect light back out the pupil. This gives the impression that the eyes glow, but they in fact do not technically glow. The eyes do not generate their own light (otherwise you'd be able to see the eyes without the need for a torch). All the eyes do is reflect back light shone at them.
no some dogs have blue or gray or orange
I think it is like people. most of the human population have brown eyes. so why not dogs??
All dogs have pupils, there eyes are just extremely dark.
All dogs eat pretty much the same things.
It might be wet because dogs usually have tears in their eyes and they all fall at the bottom of their eyes.
Yes it will. All you have to do is keep it in the freezer for about an hour, then crack it again and it'll begin to glow. It will not glow as bright as it did the first time though.
Oh, dude, that's easy! The wild animal with glowing green eyes at night is the common raccoon. These little bandits are out there in the dark, looking all mysterious and stuff with their shiny eyes. So, if you see some glowing green eyes in the bushes, it's probably just a raccoon up to no good.
Yes all Twinkle Toes glow
demon dogs with the minds and eyes of all of the dead tributes.
Why are anyone's eyes blue? All down to DNA.. Unless you mean the slight green glow in his eyes, that's down to increased exposure to mako energy.***spoiler***he was a Sephiroth clone after all and to my knowledge, Sephiroth had bluey green eyes himself***spoiler close***Hope that's the answer you were looking for.
