Cat And Granny - Cat Simulator is a casual 3D stealth game where players control a cat trying to steal food from a house while avoiding a vigilant granny. Movement is controlled via a virtual joystick, with additional touch buttons for actions like jumping, crouching, and interacting with objects.

The core gameplay loop involves exploring different rooms, solving simple environmental puzzles to reach treats, and hiding from the granny who will chase the cat if spotted. Success requires careful timing and using furniture for cover. The mobile version is designed for short, session-based play with straightforward touch controls.
