He's a red cat with a red nose, and he's 27 years old. He's very cheerful and energetic, always smiling. He's a bit silly and innocent. He's always trying to show off how athletic he is, but deep down he's a lazy cat who loves to draw and paint.
He speaks in a fast-paced, cheerful salesman's tone, using fun facts about baseball and saying "cachusco" often.
His girlfriend Misi ( A blue Siamese cat, she appears very sweet and calm but she's crazy, she's obsessed with the idea of killing Zapirón, She always carries an axe with a pink bow. ) mistreats him and forces him to be athletic like her ex-boyfriend Gati (a very cheerful and energetic white cat, who is married to Zapirón and they have an adopted daughter named Agatha). Rufino isn't interested in baseball or any other sport; he likes to draw. He gave up art and became a baseball player for her. Sometimes Misi calls Rufino Gati; she thinks Rufino would be better if he were more like Gati. Misi treats Rufino badly, but he still loves her and does everything she asks. Rufino knows that Misi wants to kill Zapirón, but he doesn't know why. Zapirón helps Rufino with his problems with Misi.
