Creamsicle loves cotton balls. If she would just bat it around, fine, but she chews on it and tries to eat it, so I have to be diligent that she doesn't get ahold of one. Yodie cannot keep her paws off my pens. She'll take them right out of the pen holder and bat them under the fridge so now I have to hide the pens. She loves to chew on my nail files, too.
