August 8th was International Cat Day. Cat owners around the globe celebrated the often puzzling furry felines. Jack H. Hetherington, PhD, had a cat in 1975 that became a coauthor to a renowned physics paper. Editing the final draft it was discovered he had used “we” instead of “I”. Unwilling to go back and replace the plural voice in the document, he did the next best thing. He added a second author: his Siamese cat, Chester, who became the coauthor, F.D.C. Willard, of the paper.
