Place the goat cheese log in the center of a large board and gently press it into an oval shape to form the cat body.
Arrange the dark rye crackers in a curved line around the cheese to outline the cat silhouette.
Position halved figs along the top of the cheese to create ears and a tail shape extending to one side.
Fill in the outline with blackberries, pressing them lightly into place to define the cat face and body.
Tuck prosciutto slices around the edges of the board in loose folds.
Scatter walnuts in small clusters near the prosciutto.
Drizzle honey over the goat cheese and figs just before serving.
Add rosemary sprigs at the base of the board to resemble whiskers.
