White Kitten is the unnamed cat in The Princess and the Frog.
The Princess and the Frog
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, Charlottle 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. The White Kitten is not seen again, but it is possible that it was replaced by Stella, Charlotte's dog.
