Stuart Little is a 1945 children's novel by E. B. White, his first book for children, and is widely recognized as a classic in children's literature.

It is a realistic fantasy about a talking mouse, Stuart Little, born to human parents in New York City.
Snowbell is a white Persian family cat, and she is voiced by Nathan Lane in the movie. Of course the name Snowbell also works for other breed of white kittens.
There's also a 5-year-old Persian cat named Prince, and you could use it as your male cat name.
