She is voiced by Donna Akersten.
Samantha is a skinny brown and beige Siamese cat with green eyes, curly brown hair, and a long thin tail. She is mostly shown wearing a long red dress, grey stockings, and black shoes.
Samantha is a mean, sassy, rude, and slutty cat with a Southern accent. She has romantic feelings for Bletch, who plans on having her as the new main star of The Fabulous Feebles Variety Hour (replacing Heidi, his former lover). Even though she's not exactly the main star of the show yet, Samantha can be shown performing in some numbers on occasions in the movie.
On the side, Samantha also works as a prostitute. One of the biggest examples of this is when Heidi caught her giving Bletch a blowjob.
