The High Cat wore only a hooded robe and sandals. He had a thin strip of beard under his mouth and a yin-yang symbol on his forehead.
The Cat refused to believe that his higher self was in any way derived from his own personality, explaining that no part of him would be seen alive in sandals. High Cat stated that he found clothes a distraction from the pursuit of spiritual and intellectual fulfillment.
