Why Do White Rabbits Have Red Eyes?

Rabbits have different hair colours: white, black, brown, gray, and so on. Have you ever noticed that the colour of their hair and their eyes is always the same? This is because rabbits of different colours have different pigments within their bodies. For example, a gray- haired rabbit has gray pigment, so his hair and eyes are all gray. But white rabbits are an exception. Though they have white hair, their eyes are red. Why? It turns out that their is no pigment in white rabbits' body, so they have white hair and white eyeballs. But the blood

in their eyes is red, so their eyes become red, too.
