Abstract: A tooth-cleaning toy for cats that is made with fin-fish skin, particularly shark skin. The meat of the fish is scraped almost entirely from the hide, leaving a thin layer of meat for flavor. The scraped skin is then cut into the desired shape, normally strips, and dried for about ten hours at warm temperature, preferably in an inert atmosphere. The resulting product is leathery and features a distinctive fish odor, which is attractive to cats. In use, the product is softened by the saliva and reshaped by the chewing action of the cat, but it maintains its integrity and attractiveness for repeated enjoyment by the animal.
