In free-to-play mobile game Cat Simulator, you take on the role of a mischievous cat. Run and leap around the house getting fed, smashing fragile objects and generally making a nuisance of yourself or go out into the neighborhood to interact with other cats, all while earning rewards that let you customize your cat avatar. Rare cat breeds and stylish accessories can be unlocked with the rewards you earn for doing challenges or bought via in-app purchases that, unusually, don't interfere with the gameplay too much.
