A cat with a piece of salmon,two mackerels, mortar and pestle Jean Baptiste Siméon Chardin (1699-1779)

The picture has something of this: mammal, cat, people, fish, two, portrait, food, indoors, still life, animal, pet, furniture.
Perhaps it’s a painting of a cat sitting on a table next to a fish hanging on a hook and a plate with a fish on it next to it.
