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 thesavesfolder withsteamcampaign01.sav,02or03(one per save slot). There may be a folder per Steam account in between. - Linux and Steam Deck (Proton):

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.
