I am familiar with the breed. I can see why they would protect you and your property!
My daughter's cat, for all of his size, is very docile. Just a big, lovable lug.
I am always amazed at the different personalities of animals. Just like humans. Only better in a lot of cases.
Much better in some cases. I have met few animals that practice deceit on a regular basis. My little dog does now and then, but not often.
