Adriana Grande's voice does not sound like her character cat on Victorious as she has to make it higher in pitch to suit her role. She portrays a happy and positive character which you can also call hyper. Cat is rarely fund in a bad mood and always seems to be in a good mood but silly sometimes.
Ariana Grande is my best friend. I love her high voice as Cat on Sam and Cat, and her normal voice. I have her private phone number. I call her and text her all the time. She is so sweet and kind. she flirts with me until like 12:00 AM.
