Dog Drawing By Breathed Berkeley

In addition to his syndicated cartoon work, which has produced eleven best-selling cartoon collections, he has also produced five children's books, two of which, A Wish for Wings That Work and Edwurd Fudwupper Fibbed Big, were made into animated films. Since 1992, he has designed a greeting card and gift ensemble collection for American Greetings, featuring the "Bloom County" characters Opus, Bill the Cat, and Milquetoast the Cockroach. Breathed's writing has also been featured in numerous publications, including Life, Boating, and Travel and Leisure, and he produced the cartoon art of the film, Secondhand Lions, which featured a strip called Walter and Jasmine. The panels he drew for Secondhand Lions appear in Opus: 25 Years of His Sunday Best, in which Breathed terms them "the comic strip that never was".
Breathed has been a supporter of the animal rights group PETA and illustrated the cover of their Compassionate Cookbook, T-shirts, and other merchandise.
Breathed cameos as himself in the short film Tim Warner: A Life in the Clouds, a fictional tale about an unhappy cartoonist and his unfunny strip, The Silver Lining.
Breathed adapted his children's book Edwurd Fudwupper Fibbed Big into a short film produced by Disney. Intended originally to be released as a bonus with a theatrically released Disney animated film, the movie as of April 2007 was not exhibited commercially in any format. According to Breathed in an online interview, he states that the film is "an unmitigated technical disaster" and that it was "unfinished and unshowable." His book, Red Ranger Came Calling was adapted into a musical and produced as a Christmas show by Seattle's Book-It Theatre in 2004-2005.
