Yes, as it does for most felines.

Tigers, as with all cats, have a reflective layer behind the retina. This allows them to use the light twice in the retina, making it much easier to see at night. When cat's eyes appear to glow, you are seeing the escaping reflected light from this surface.
In a phrase which is not grammatically correct such as the above, it's kind of difficult to tell.If the meaning you were going for is along the lines of "her dark eyes reflected the stars" it's not a metaphor.If the meaning you were going for is more like "the light reflected from her dark eyes like stars" that's also not a metaphor, it's a very similar concept called a simile.If you were going for something like "The reflections from her dark eyes were stars in the night", then yes, that's a metaphor.
Because cats are closely related to lions and tigers. Lions and tigers are hunters, so their eyes reflect in darkness to hunt prey, even in dim light. Domestic cats are hunters, too, and they related to lions and tigers, so their eyes reflect in the dark.
Reflected
Among the light rays falling on the window, some get reflected and others get refracted. If some of the reflected rays reach your eyes, you would be able to see the image. But a dark wall would absorb all rays.
We are able to see the tree because light is reflected into your eyes. We see reflected light.
Reflected
We can see because our eyes are receptive to the lightwaves reflected off objects.
Animals eyes do not glow, their eyes only reflect light. This reflection of light, which appears to make the animal's eye glow, is called eyeshine and it is caused by the tapetum lucidum, which is a layer of tissue in the eyes of many vertebrate animals. The tapetum lucidum allows the animal to see better in low-light situations (such as after dark) by reflecting the light back into the retina. When a photo is taken of an animal that has tapetum lucidum in it's eyes, the light reflected from the flash of the photo often makes the eyes appear to glow. The same thing occurs when light is flashed into the eyes of animals that contain tapetum lucidum after dark.
Yes. The only reason you can see anything is because of light and reflected light. If there is no light, then your eyes don't detect anything. Our eyes work like cameras. When there is little to no light, cameras cannot focus on or "see" anything, just like our eyes.
If you can see the light reflected, then it has hit your eyes, and your brain is processing it as the sense of sight, if you cannot see it, then it has reflected somewhere other than your eyes-IE; back into space, or it is a wavelength of light that the human eye cannot detect.
