I read that they were bred as temple guardians, and our old moggin was living proof. We had someone try to con his way into my house while I was at work one night, claiming that a pizza had been ordered for my address. When he knocked Chippinmog was there, growling like a little dragon. The door was not opened, the conversation ended with the offer of the pizza for free being refused. Peering through the front window, the villain was seen retreating to his unmarked van, empty handed. An excellent cat.
Smudge has a bit of that in him. He's the only cat I know that when someone knocks on the door, he growls and runs towards it.
I thought it was just because he's an aggressive bad-tempered sod.
I turned over in my sleep, in bed, a few nights ago and my hand must've 'flopped' in front of him and the rotten barsteward savaged my hand.

He's sweet sometimes though; purring and head butting us. This starts mostly about two hours before his breakfast or dinner.
