Paw Encyclopaedia

Background
The Paw Encyclopedia is an encyclopedia filled with paw prints of cats collected by Itachi Uchiha and Sasuke Uchiha in their youth. The paws in the encyclopedia range form nimble house cats all the way to the Two-Tailed Monster Cat. It was originally a game between the two brothers to collect the paw prints, but Nekobaa turned it into an actual book. The last paw print collected was that of Nekomata, which was obtained by Sasuke Uchiha.
