ere never aware that theywere being observed. This study could be improved by reducing the amount of variance between theferal and indoor cat groups. Uniform diets and feeding times would probably have yieldeddifferent results than what was found in the current study. It would also be interesting todo another study that examines the degree to which the head shaking behavior isgenetically determined. According to an article by Moltz (1965), fixed action patterns canoccur in the absence of the normal releasing stimulus. In the case of head shakingbehavior in cats the releasing stimulus would be food. If head shaking behavior fits intothe category of fixed action patterns, cats might shake items other than food. Futurestudies could look at how frequently cats perform this behavior on nonfood items, such astoys. Differences between cats who have been food deprived and those who have notcould be compared. ...
