Cat Life Simulator: Devil Cat

Cat Life Simulator: Devil Cat is a mischievous first-person sandbox game that’s now available for you to play on our website. You take control of a sneaky cat who’s just moved into Granny’s house. At first glance, the house seems calm—but things quickly turn chaotic once you're invited to join a prankster cat gang. Your job? Cause the most chaos possible while avoiding Granny’s watchful eyes.

We know people love playing cat simulator games on our website. That’s why we decided to include this one—it’s silly, clever, and packed with moments that will make you laugh. Every room has something you can mess with. One moment you’re pushing a flower pot off the shelf, and the next you’re dodging Granny after triggering an alarm clock. It’s a pure chaos simulator, but with a playful twist.

You won’t find a story-driven game here. Instead, this is all about experimenting with the environment and seeing how much trouble you can cause without getting caught. The more chaos you create, the more points you earn. You can spend those points to unlock prank tools or change your cat’s look.

Let’s play the game on our Y9FreeGames website and see how long you can stay out of Granny’s reach.
