"Moby Dick" pet food
The meat from the whales that were hunted out of the Richmond whaling station was primarily used for dog and cat food. The Caito family, which ran the whaling stations out of Point San Pablo, had their own pet food label, "Moby Dick". According to John Caito Sr., their biggest customer was Cal Can, a manufacturer of dog food.
