Tigers

Tigers have many color varieties–white, black, and even blue.

An excerpt from the article 32 facts about tigers

The blue tiger is called the Maltese tiger and is probably a variety of the Bengal tiger. All white tigers housed in zoos are descended from a single father named Mohman. These tigers have more health problems like cleft lip and palate, scoliosis, and strabismus. This is a result of inbreeding, which provides zoos with white cats.
