Codex pets are currently supported on macOS and Windows.

Download manually
Use a pet card download button to get a zip, inspect it, unzip it, and move the pet folder into your Codex pets directory.

Activate in Codex
After either method, open Codex desktop and select the pet in Settings > Appearance > Pets.
