White tigers are at the top of their food chain and have no natural enemies. Their primary diet consists of large ungulates, including deer, water buffalo, wild cattle and wild pigs. As of 2014, most white tigers live in zoos but wild ones are occasionally reported in India. The white tiger is a color morph of the Bengal tiger resulting from a recessive gene that knocks out the orange pigment. White tigers are not albino as they produce black or brown pigment. Most white tigers have obvious stripes, but a second recessive gene makes the stripes pale and results in tigers that are nearly all white. White tigers are prone to crossed eyes and kidney and spine problems.
