Its my understanding that a "tiger" phase is an animal that is part ruffuie, usually 50%, that has more of the dark blotches and less of the orange/yellow background color than you normally see. I dont think its genetic like the stripes, though I could be wrong since I dont have any.

“There is a grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one; and that whilst this planet has gone on cycling according to the fixed laws of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved.” -C. Darwin, 1859
