I had a neighbor abandon a cat years back, she was missing a hind leg but could she run! She had a kitten (that's how I kew she was female). I would leave them food and go inside, eventually she would meow at the door when she was hungry, I was never able to fully tame her but she knew where to come for food. She would sit on the thresehold of the door and watch us, but that's as close to coming in I could get her. She dissappeared one day and I was never able to find out what happened to her. It sure makes me mad to think how often people do that to cats!
