The instructions given to participants for this assignment were simply:
"Draw a cat that represents your current mood."

Participants could interpret these instructions however they wished. The goal of this prompt was to allow people to let loose a little and have fun, while also expressing their current emotions. Many of the drawers are not artists by trade. They expressed nervousness to me at having to do something that they felt they couldn't do well. However by the end of drawing these people were almost unanimously in better spirits. By drawing--something they never normally do because they are "bad" at it--they felt like they had let loose and allowed themselves to doing something fun and silly just for the sake of it.
