Blue is a cat who appears in the U.S Acres Comic Strip. She keeps Cody out of mischief and saying stupid things.
As her name states, Blue is a blue kitten with some white parts on her. Her eyes are vastly different from most of the franchise's cat characters, as they are farther apart and the pupils are larger. Her nose is also drawn differently, resembling a real cat nose.
Blue's personality is mellow, albeit a bit downtrodden, as she must deal with Cody's antics and keep him out of danger or correct him when he does something stupid. Regardless, she is patient with Cody and loves him just the same.
- Cody and Blue are the only U.S Acres characters not to make any animated appearances.
