Little footprints on the pages of history

Somewhere in 14th century Croatia, a scribe must have had a few choice words for his pet cat after kitty left his little paw marks on the pages of the scholar's book. The discovery was made by Ph.D student Emir O. Filipović in the Dubrovnik State Archives. (photo)

Filipović snapped a photo of the prints and posted them online, causing an international Twitter frenzy. Smithsonian Magazine chronicles the evidence of the cat's bad behavior on its blog.
