String on a stick would be a toy for cats they would play with it, follow it around, and when they play with it there should be a 10% chance of it breaking, the toy should make them happy, the happier they get u should get a little XP for it. They should have a happy bar that would act like r XP bar, to see it u should hit LT then it would pop up where your xp bar would be then press LT again on the cat to remove it.
