Why tiger's eyes are red?

Question

Answer 1

I think it's the same as any other animal with red eyes; it's light reflected off the blood vessels of the retina, which is the layer at the back of the eyeball that recieves the light.

The same thing happens when you use a camera flash.

Answer 2

because  a tiger wants to make another animal to be afraid    immediately when  that animal see the eyes of  a tiger

Answer 3

Where did you get that?  They are NOT red, they are yellow-orange.

Answer 4

The iris (colored part) of a tiger's eye is yellow-orange or, for white tigers, blue-grey.  However, if you shine a light at a tiger or other cat's eyes in the dark, they will reflect bright green, red, or yellow light back at you.  This is because cats have a reflective membrane (the tapetum lucidum) lining the back of their eyes, to help them see better in the dark.  The tapetum lucidum reflects light back to the light-sensitive cells in the retina (similar to the polished silver reflector on an old-fashioned train lantern), allowing them to see at very low light intensities.
