Verdict
The clearest difference is ads: Kon21 at none against Cat Simulator's shown. Kon21 also leads on update cadence (every 4 days vs every 5 months) and monetization model (free vs free with in-app purchases). Cat Simulator's advantage is ratings volume (12 vs 1) and iOS requirement (15.0 vs 26.2). On price, rating, in-app purchases and device support there is nothing between them.
