Below is a video of Mugsy the Cat. And yes, he saved a boy from two hungry, vicious alligators. As you can see, one alligator emerge from the swamp but the cat immediately launches an attack. The croc moves backward a bit.
The cat attacks again and the two animals stare at each other. The croc then retreats, but came back again. Suddenly, another croc came out from the water but the brave cat scares him away too. The cat returns to his owner, a boy sitting only a few feet away. Super cat!
