My cinnie girl is still a bit vocal and can be nippy at times. When she first got in she tagged me a bunch! My calico has never been a biter but boy she sure is vocal. Her posture often indicates that she is going to strike but I figured I would have to just see what happens and to this day she has never struck. Shes all talk! But I am super attached to her. My enchi is still pretty nervous when I handle her and she is still a bit nippy too.
