Katerina is a female kitten with a white complexion. She wears a light green and blue knee-length dress with yellow buttons, a light green bow tie on her head, a pale yellow camisole, green panties, white ankle-high socks and green and white sneakers with yellow colored laces.
- Katerina scatters the word "meow" throughout her sentences in the same manner that her mother did in "Mister Rogers' Neighborhood".
