The ONLY way to produce a tiger or lion with a white coat is through inbreeding generation after generation after generation. The same gene that causes the white coat causes the optic nerve to be wired to the wrong side of the brain, thus all white tigers are cross eyed, even if their eyes look normal. They also often suffer from club feet, cleft palates, spinal deformities and defective organs. You can end the misery by just Saying NO to any place that breeds or exploits white tigers.
