The little kitty just runs and hides every time. Silver, the older kitty is just too old to run so he stands his ground. He growls and hisses and has tried to strike the dog...if for no other reason then to show that he means business (a pissed off cat can be a scary thing). Lady does seem to be afraid of him and in time i can see them leaving each other alone. But with the little kitty, if all she wants to do is run, i think that will be a more difficult situation to deal with.
