Lumi, by contrast, uses growling as the basis of her talking. When she growls, it does not mean she’s warning that she’s about to scratch or bite. She growls and grumbles when she is excited about breakfast, birds, or play, as well as when she is annoyed, or subsiding from some state of annoyance or excitement and telling me about it, complaining and confiding, just making conversation.
I don’t have video yet, but am working on it.
