Hmmm, you had me until the you are not a cat part. Much as I would love to be a cat, cat's can't spend money, no one would let a cat do that, and I really don't like cat food, so no thanks
You get a million dollars, but for the next three years you are the babysitter of an evil young child who hates you. You must babysit when requested, you must do as good a job as you possibly can, and the parents think their child is an absolute angel, and will not listen to you
