Lions and Tigers can have fertile offspring, eh? I gotta see if I can find a picture of that. Bet it's cute looking.
I always thought the Liger was just something made up in the fevered minds of the Japanese.
Neat study too by the way.
Edit: Huh weird. They're bigger then either of their parents... and are only made by Male lions and female Tigers... is it not possible to work the other way? That's called a Tigon... weird.
Just a correction a Tigon comes from a Female Lion and a Male Tiger. A Liger is the largest Cat on earth and is from a Male Lion and a Female Tiger.
A Liger
Here is a video
That's what i said. Just the wierd paragraphs due to the edit made it look funny. The "That's called a Tigon" thing was in reference to the opposite of the Liger which is the largest etc etc.
