|This article is about the fictional character. You may be looking for the episode, or Ruthie (real character).|
Ruthie is a bright, intelligent young cat. Princess Carolyn also calls her poised and funny.
Ruthie looks similar to her great-great-great-grandmother. She has pale pink fur with a ponytail on the top of her head that is held up straight by two green bands and comes to a curl at the top.
She is seen wearing a light purple spacesuit with an elaborate red brocade-style collar with a white decorative border, two checkered purple patches on the sleeves, and light pink space boots with red stripes with light purple soles and straps.
She wears a gold necklace with an upside-down triangle and red dot in the center that has been passed down for generations and was worn by Princess Carolyn herself.
Ruthie first appears in the episode of the same name, shown in the 2120s giving her middle-school class, taught by Mrs. Teachbot, a presentation about her ancestor Princess Carolyn, about when she had a particularly awful day.
However, it is tragically revealed that "Ruthie" was made up by Princess Carolyn as a means of coping with the trauma of multiple miscarriages.
