Yes I think they know full well how hard they can bite if they want to. Mitzi sometimes goes through the motions of biting if I am doing something she doesn't want me to (such as spraying her) she doesn't really want to bite me but she lets me know that she could.
Somewhere in another universe, dear brother, you got saved.
If I am doing something Chy doesn't like, she warns me verbally. She says, "No, don't. Stop it. Go away". If I keep on, she will then say, "Ouch" meaning if I don't stop, I will be saying ouch. She is quite a character.
