Hello! i Just purchased my first ball python(first snake for that matter) at the raleigh nc repticon this past weekend. Its the second day, the breeder said she was on empty the day i got her. I went to feed her frozen thawed, she missed the first strike, and nailed the second strike and was constricting the mouse. From all the research I have done everyone has said give the mouse a slight tug to mimic resistance and struggle. When i gave the mouse a slight tug she hissed and let go of the mouse right away. I then attempted to feed her the mouse again she appeared completely uninterested and even a little fearful of the mouse backing her head away. I decided to call it quits for the day because i dont want to stress her out. Have i ruined frozen thawed for her? Thanks-
