Nature, I guess these animals would have more senstive 'rods' and 'cones' in their eyes, which are more adept at picking up light of lower intensity than humans can. Hence, what appears as darkness to us isnt probably really dark. Im sure these animals too wont be able to see anything in absolutely pitch black darkness.

What we see in the cats' eyes is probably the light relected off their lenses / vitreous humor (I assume). Nearly blind animals, like bats, obviously depend on other forms of 'sight' (echo location in this case) to 'see'.
