Bill the Cat

Bill the Cat, or Bill D. Cat, is a fictional cat appearing in the works of cartoonist Berkeley Breathed, beginning with the comic strip Bloom County in the 1980s and continuing in Outland and Opus in the following decades. Bill also appeared in some of Breathed's illustrated children's books, including A Wish for Wings That Work, which was also made into an animated Christmas television special, and also on greeting cards and other sundry merchandise. The cat's most frequent spoken sentiments are "Ack!" and "Thbbft!", unlike most other animals (and children) in Breathed's work, who not only can speak English, but have advanced vocabularies. The former is a result of his regularly choking on hairballs, the latter sound an approximation of the "raspberry".
