Hey, markys! Try to navigate to Settings > About phone. From there, tap where it says Android 11 and then repeatedly tap where it says Android 11 again until the dial appears. Move the dial from off to “11” until the 11 appears and the cat emoji appears.
To activate the Cat Controls, do the following. Long press the power button to access the new power menu. If the controls don’t already appear, tap the 3-dot menu button on the right side of the screen near the middle of the phone and tap the Add controls option. Tap the See other apps option the bottom left corner and tap the Cat Controls option to add the cat mini-game to your power menu.
I hope it works! Anyways, have a nice day ahead. Stay safe and Godbless!
