The rules are super simple and easy enough for a 6 or 7 year old to grasp. The goal is to make sad pets into happy pets using food, medical and love cards to fill their needs. Doing this lets you flip them to their happy side which scores points and other rewards like picking up cards for free.
The card art is well done and fits the cutesy theme perfectly. Playtime is around 20 min like the box says so the game never overstays it's welcome. The box size is also appropriate for the game with no empty space.
