This is the fake, shadows are all wrong Photoshop job of a standing cat transformed into a medieval battle cat. That look in his eyes -- you can tell he's out for blood. Or maybe he's just out to eat a bunch of grass then throw up in the house later. What do I know, I'm not a medieval battle cat expert. You know what I got in history class? Bored. I'm kidding, history is fascinating. Stay in school, kids.
Thanks to Richard, who agrees the Photoshopper should have given him a riding mount.
