That Ginger Tabby cat

We have a male ginger tabby in the neighborhood who roams free. Now, our RIP big tomcat Brownie would have told him in no uncertain terms that this place was his territory and off limits. So, today when the tabby walked on our deck right when I was petting Butzie in front of the cat door to the deck I said, "Go tell that Tabby that this is your territory!" She looked at me and said "What are you nuts?"
