Hi Carl, believe it or not, he routinely attacked Raccoons. He would engage them in the driveway when he heard one of our cars coming. When the headlights hit the Raccoons they would turn to run and give him their back. He took it. He would tear into them for a second and run. He attacked everything. Dogs, a plumber (who screamed devil cat all the way down the driveway) our housepainter (even after being warned that this was not a pet). He attacked invading Toms without puffing up. Weird, it freaked them out completely. He wouldn't posture at all, just go right up and get busy. Now the property is all happy valley, Robins and bunnies and rainbows.
