Ligers became stupidly-popular since Napoleon Dinomite was released. Since then, anyone who saw another person drawing any type of feline was tormented by others, their work being mocked by them asking over and over, "Is that a liger? Is that a liger?"
Ligers were not only bred for use in magic. In big-cat farms, where lions and tigers and other types of big cats (such as leopards, jaguars, moutain lions, ect.,) are held, and if lions and tigers are kept in the same cage, something will happen eventually.
Ligers are normally much larger than both lions and tigers and are reported as the largest big-cats ever. From nose to tail, the liger may be up to 12 feet long. Male ligers will normally grow a blond-brown mane. Both male and female ligers will have some sort of stripe pattern down their back and possilby limbs. There have been no reported fertile males, thus, ligers haven't been able to reproduce with their own species.
Most ligers seem to be born sterile (this is not unusual for hybrids) - there are recorded instances of ligers breeding, though few and far between.
Ligers, and their cousins Tigons (sometimes also referred to as "Tions" or "Tiglons") do not currently have a scientific name, but might be called "Panthera leo/tigris", or something similar.
