This is a little “find the hidden cats” game. You literally just have to click on all of the cats, of which there are about 300, and then you “win”.
Some are hidden in drawers or behind curtains. A few move and have to be found several times. Some blend in with the wallpaper, some don’t actually look much like cats, and some are tiny.
But it’s a nice, quiet little game and passes the time, and sometimes, that’s fine.
