Yes, he was a sweet and beautiful cat, and yes, he was extraordinarily trusting and generous, but he was still a kitten. He’d streak maniacally through the staff room. He’d knock your work to the floor out of pure playfulness. He was too immature to know who really needed him, and he sometimes wouldn’t take no for an answer when a patron wanted to be left alone. At Story Hour, his presence made the children so rambunctious and unpredictable that Mary Walk, our children’s librarian, banned him from the room. Then there was Mark, a large puppet of a child with muscular dystrophy. We used Mark to teach schoolchildren about disabilities. There was so much cat hair on Mark’s legs that we finally had to put him in a closet. Dewey worked all night until he figured out how to open that closet and went right back to sleeping on Mark’s lap. We bought a lock for the closet the next day. But nothing compared to his behavior around catnip. Doris Armstrong was always bringing Dewey presents, such as little balls or toy mice.
