About this encyclopedia
Entries cover both fictional cats (movies, books, comics, video games) and real ones (presidential pets, military mascots, internet celebrities, public-figure rescues). Legacy summaries still need individual source review. Unreviewed expanded biographies are withheld; short reference notes and summary-only detail pages carry noindex. The methodology explains the review scope. Have a famous cat we should add? Tell us.
