This is an idiotic headline. Anything that could kill a mammoth or short-faced bear is not to be messed with. If the sabre Tooth was still around you would see Grizzly bears run from this monster.
Ohhhhh, I dunno about that.
A full-grown male grizzly bear is about three times the size of one of these cats.
My money'd be on the grizz.
Remember this guy?
