Pets

Hey everyone, I read on here couple of time about pets one give us option to pay in cash or stars or lower the stars. And two wouldn't it be nice we could feed our pet and get a higher XP point or money for it??? Maybe the highest you can go is a 50 or 100?? Like in the beginning it be 5 points and you have a bar that have to be fill up before going to next level of getting more XP point or money all you have to do is feed the animal. Feed it once a day
