The practice of potted cats originated in Japan in the early 15th century, just before the beginning of the Fap Wars. At the time, all Japanese art was dominated by Hello Kitty merchandise. The Emperor of Japan, though resplendent in his pastel pink armor, was interested in developing new art forms. The rest of the Japanese nobility was just sick of being up to their eyeballs in Hello Kitty. The Japanese, on the other hand, did not have a NEDM fetish but did recognize the potential for bone binding. They found that it was easier to reshape bones by placing them in pots.
