Once stereotypies do develop, you should try to reduce them, even in the case of scar-on-the-brain-type stereo-typies. An animal like Luna may not be suffering, but the constant stereotyping itself interferes with an animal’s quality of life and her nervous system is operating in a totally abnormal manner. If I had been allowed to do stereotypies all day, I would have never become a professor and I would have missed many wonderful experiences. The people who ran Luna’s shelter did manage to get her stereotypies down somewhat by moving her to a different pen away from the food preparation area.
