Albinism is caused when a human or animal's cells are unable to produce melanin. "Melanin is a dark pigment that results in a normal coloration of skin, scales, eyes, and hair."-mdc.mo.gov. A lack of melanin causes the animal or part of a animal to appear white or pink. Being white doesn't make an animal albino, the true test is if the animal has pink/violet or light colored eyes.
