I know it's probably normal...but she whines from sun up to sun down, no matter what! She's been fed, she's been changed, she's sitting there playing and seemingly having a good time, and yet she's whining! Or, if she's having a good time playing, and she's not whining, she will start if I say something to her. What is that?! What a horrible sound, constant whining. Is something bothering her that I haven't figured out yet or is this a normal thing? Please help!
