Unlike other mobile games, this isn't filled with ads, gambling, or trashy bloated UI elements. "Rare" in this game doesn't refer to pull rate, but simply that a cat is attracted to specific toys or food, all of which are always readily available at the in-game currency shop. You can spend money to get this currency, but that's as far as it goes. Really, you shouldn't though because this is meant to be played in small doses over a long time period.

It doesn't pretend to be anything grander than it really is. You feed cats, place toys for them, take pictures of them, and that's it. The game actively discourages you from wasting your time staring at your phone since cats will only appear when the game isn't open. You just check in whenever you feel like it.

It's the only mobile game where you actually play the game instead of it playing you, and for that it may very well be the best of them.
