Oh my goodness! Did they have any wildcat in them?
They were both half domestic. The other half was what we called a Lynx. They had the tufted ears and cheeks, and were pretty much solid muscle and very territorial. I was the only human (or animal) they would accept.
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.
