# Katten Project: Plus+ and Touch Pets server reimplementation

Python modules provide account, session, cloud-save and leaderboard endpoints, while research notes describe XML elements parsed by Touch Pets clients. The project also includes a script that patches a user's game binary to stop using HTTPS.
