In Hit-Point's super simple sim, the Japanese-only (but perfectly playable without being able to read the lingo!) Neko Atsume, free for iOS and Android, is all about cats. You put food out in your backyard, along with some toys (and since they're cats, "toys" can also mean "boxes and bags"), and cats come to play with them. You watch the cats relaxing or playing. You take photos of the cats. The cats, when they leave, leave you some fish in return for their fun and food, which can be then spent on buying more enhancements for the play area. If you're lucky, they'll leave golden fish, which can be spent on expanding the area or even better items, though if you're impatient you can buy more golden fish for optional in-app purchases. And that's it. It's essentially Sea Monkeys, only, you know, better because it's cats, and they have cute little cat bums. Though it is all in Japanese, a little experimentation with the buttons will help you figure things out quickly.

There are different types and colours of cats, some who parody pop culture, and your goal is simply to see and entice as many as you can. All you need to do is check back in with the app periodically to refill their food dish, which is free, although different food types can be bought with fish, and snap new photos if you like, and after a cat has visited you enough to take a liking to you, they may leave you a special item trophy as an achievement. Neko Atsume isn't really something you "play" so much as it is a simple pocketful of virtual pets you check in on once in a while, and if you want something absolutely adorable and low key to put a smile on your face, this is definitely it.
