My little tomcat, Dinky MacDougal, has been an indoor cat, seeing very few humans but me, for about 6 years. If anyone other than my grandson shows up, Dinky attacks.
He will stand between my feet and threaten the UPS driver with all kinds of mayhem.
I hope I outlive him, no one else could live with him.
Is he a mean critter, or just defending his space, the best that he can?

Cats usually don't defend territory...but they do defend animals that they are keeping to use as food later on.
