Ginger, my long haired orange cat, is very territorial! Once a young kitten walked pass my front gates and she chased the poor thing away, clawing and biting. One back alley cat came into my yard once too, probably looking for food. She hissed and scratched and scared the poor thing away as well.
Despite all those, I still love her! She keeps all the mice at bay. :)
But she's so shy though! I can't seem to get a photo of her where she is looking into the lens!
