If the poor cat would stand his ground-Frankie would get over it. One of my Mal's(who was 2yr old rescue) would chase a cat, get him by the neck and shake and break their neck. If a cat wouldn't run, it would rub all over him,purring and he would not even pay attention to it. It's usually the RUN that get them! But a cat doesn't want to risk it.(You can't blame the cat, it's a risk!)
