Cavemice is one of the many adventures of Geronimo Stilton. It is about Geronimo's prehistoric ancestor named Geronimo Stilton. Stiltonoot works for the Stone Gazette, as its editor. His job is to carve the news into slabs of stone, so that people can read it. This is because printing hasn't been invented at this point of time. Life in prehistoric times is full of adventures of various kinds, which include fighting saber-toothed tigers and fleeing from a t-rex. Stiltonoot has chiseled all of these entertaining stories onto tablets of stone, so that people can continue to read them, over the years.
