It is possibly Charlotte's pet cat. It is seen at the beginning after Eudora reads The Frog Prince to Tiana and Charlotte. When Tiana says she'll never kiss a frog, Charlotte puts a frog mask on White Kitten and starts pushing it in Tiana's face. But when Charlotte starts kissing White Kitten, it jumps up and gets stuck on the ceiling. Eudora then gets it off the ceiling and takes the mask off the horrified White Kitten who crawled away. The White Kitten is not seen again, but it is possible that it was replaced by Stella, Charlotte's dog, or he passed away.
