These pics came from AZ.
Yes, the mule killed the mountain lion. The lion had been stalking them for the better part of the morning, on the way out to a hunt. They were pretty sure it was after one of the dogs. The cat ambushed them, and the mule pictured tossed its rider and went into attack (defense) mode, the horses and the dogs scattered leaving only the mule to handle the attack. Unfortunately, it wasn't until it was almost over that one of the guys was able to start snapping pics. The mule finally stomped the cougar to death after biting and throwing it around like a rag doll. The dogs wouldn't even come close until the mule settled down.
The cat was still alive here and trying to fight back.
The mule stomped the cat, then pinned to the ground and bit the heck out of the dead cat several more times.
The cat was pretty much dead by now, then the mule picked it up again and whipped it in the air again, then stomped the dead cat again for good measure!
Note the dog audience!!
Gives new meaning to the term "BAD ASS"!!!!
