Eddie is the cat from the northeast U.S., who manages a lot of the aspects regarding Cats 'n' Briefs, including the socials, the Patreon, and accepting commissions.

He assists in layouting a lot of the drawings, as well as managing clean-up and the coloring process.

His fursona, Eddie, is arguably the "face" of the Cats 'n' Briefs iconography.

Oiruse is the cat from Spain, who is the heart and soul behind the project.

He does all final layouts and all backgrounds, and is the main reason why the Cats 'n' Briefs project exists. With the intention of creating artwork never seen before in the fandom, Oiruse brings in a sense of fun generally not seen in the furry art community.

His character, Tidbits, is the siamese cat opposite to Eddie. His character is originally a pirate ship janitor, but generally is seen in the more familiar AU suburban environment with Eddie and Eddie's father, Mateo.
