BIOPREDATION - MICE and RATS
Mice and rats eat many things, and they are able to cause damage to books in their search for food. The damage each cause is similar but some are larger and cause more damage.
The items pictured were all damaged by one or the other. The first image shows some damaged boards with some additional damage to the pages. The second image shows some damaged spines. In one case, the perp even ate through the clear protective cover. The third image shows a Real Photo Postcard (RPPC) damaged at the edge.
