Oh, she doesn't trill? Nomally if a cat's sleeping and you touch it it will go" uurrdrdrdrdrr". Most cats I have come across trill. One cat used to almost thank me when he was meowing at the door to come in. When I let him in he'd go rrdrdrdrdrr" as if to thank me. He was a lovely natured cat too. Had to have him put down as he was badly injued by a dog.

Your cat sounds unique. I can imagine her huffing too. She's obviously the ruler of her property. Great you get a real meow out of her. That would be lovely to hear. Have you thought about trying to record her?
