What is the name of Tom's girlfriend in some cartoons?

Tom’s girlfriend in some Tom and Jerry cartoons is Toodles Galore.

Toodles is usually depicted as an attractive white female cat wearing a large blue bow. She is Tom’s most frequently recurring love interest during the classic MGM era, although Tom is portrayed as a flirt and pursues several other cats across the series.

Toodles first appeared in Hugh Harman’s 1941 short “The Alley Cat,” alongside Butch, before being integrated into the Tom and Jerry series. She is typically silent, so her identity is established through her design and the romantic rivalry surrounding her rather than dialogue.

A frequent mix-up is “Toots,” another cat who appears in several shorts, including “Puss n’ Toots.” Toodles and Toots are separate characters. Toodles also appears in later productions, including “Tom and Jerry Tales” and “The Tom and Jerry Show,” though her design and role vary.
