I like the idea of keeping many cats as happy as they can be in real-time simulation.
The gameplays seems nice at the beginning, but quickly turns into a simple (but quite demanding) clicker. I would appreciate to see all of the cat states on screen with all the necessary buttons for every cat available without extra clicks.
Simple and clean graphics work smoothly for this game, well done!
And a little advice fot the future games: account for different screen resolution (not necessary to higher than yours, you can try lower options, like 1280x720 or even 800x480).
