This reminds me of a Calico cat we had when I was young. Her name was Patches and she loved our Beagle doggie, Ralph.
One day an elderly neighbor visited us dragging her doggie along on his leash. He was a real meanie and was growling at our sweet-natured Beagle. Patches was sitting on our stereo console watching intently as the snarling dog approached Ralph. All of a sudden that mean dog went for the throat of our beloved doggie like a ferocious coyote! Not but a few seconds later our kittycat was on that mutt like the Tasmanian devil! Patches was spinning around that dog's body like a gear, biting into him and tearing his fur off with her claws and teeth!!! He yowled in fear and pain and couldn't get away from her fast enough!
Ralph just stood there is awe watching Patches do her stuff. It was amazing! Patches loved Ralph so much, she risked her own life to save him. Ain't that something?
