Where is my save?

Close the game first: it may keep the file open while it runs.

  • Windows: open %APPDATA%\Glaiel Games\Mewgenics\ and look for the saves folder with steamcampaign01.sav, 02 or 03 (one per save slot). There may be a folder per Steam account in between.
  • Linux and Steam Deck (Proton): ~/.local/share/Steam/steamapps/compatdata/686060/pfx/drive_c/users/steamuser/AppData/Roaming/Glaiel Games/Mewgenics/

Breeding room

Use the numbers the game shows for the room. Stimulation raises every inheritance chance; Comfort only changes how likely cats are to breed, and drops by 1 for each cat over 4 in the room.
