Rusty looked like a real tough guy! It's amazing that he allowed himself to become even an occasional house cat.
And he was very intelligent, Kelley. His favorite spot in the house was the mat by the kitchen sink. He never roamed around to claw on furniture. He did that on trees outside. If he had to relieve himself, he would go to the door and meow. If he was alone in the kitchen, he would would find one of us in the house and let us know he had to go out.
He never bit or scratched anyone either. He reserved that behavior for his frequent fights with other feral toms in the woods. He was pretty good-looking too especially in the winter with his thick coat, mane and bushy tail. He probably had some Persian in him. His right ear never stood up straight, though, because of some wound he had as a result of a fight.
