Photoshop.......I have seen one of these animals..er...test tube experiments. A male lion and female tiger have genes that regulate offspring size. a female lion and a male tiger dont have the regulating code.....if you breed the pair, you get the sterile liger but an added bonus, the liger can be 2-3 times the size of the parents. These things are monsterous cats. No B.S., do an internet search, im sure it is online.
