I think this is a great entry! The game is simple, the art is cohesive, and the game feels responsive. The start button pop animation was great. I also loved the bell tolling the instructions. Getting caught reminds me of a FNAF-lite anti-reward. The art for it is so different it works well.
Only thing I can think of is getting more feedback on the progress of the couch. You could incorporate progressively damaged couch, or have it dynamically damaged depending on where the cat was.
Aesthetically, when the cat isn't scratching, it could be doing "innocent" cat things to help sell the ludo-narrative.
Sweet game!
