The brothers composed multiple songs, but only the title song and "Scales and Arpeggios" were included in the film.  Desiring to capture the essence of France, the Sherman Brothers composed the song "The Aristocats". Disney film producer Bill Anderson would ask Maurice Chevalier to participate in the film.  Following the suggestion, Richard Sherman imitated Chevalier's voice as he performed a demo for the song. Chevalier received the demo and was brought out of retirement to sing the song. Deleted songs that were intended for the film included "Pourquoi?" sung by Hermione Baddeley as Madame Bonfamille, its reprise, and "She Never Felt Alone" sung by Robie Lester as Marie.   For the show-stopping number, the Sherman Brothers composed "Le Jazz Hot", but the filmmakers preferred "Ev'rybody Wants to Be a Cat" composed by Floyd Huddleston and Al Rinker .  Lastly, a villainous song was envisioned to be sung by Edgar and his assistant Elmira as a romantic duet, but the song was dropped when Elmira was removed from the story. 
Techniques used by the textile industry to avoid pilling include singeing the loose fibers protruding on the surface of textile , and spinning the yarn with a high number of twists per inch . Some fabrics are chemically treated during the manufacturing process in order to reduce their propensity to pill. Polymeric coatings are sometimes applied, to bind fibers into the fabric surface and prevent initial fuzz from forming. Polyester and cotton fibers are sometimes modified to be of lower-than-normal strength, which results in pills detaching easily from fabrics, once they are formed. Cellulase enzymes are sometimes used on cotton fabrics during wet processing , which removes loose fibers. 
Although Slaughterhouse-Five made him a famous, bestselling author, Vonnegut struggled with depression in the midst of his literary success. After getting divorced in 1971, he lived alone in New York City and had trouble writing. His son became psychotic, and although he married his second wife in 1979 (and they adopted a daughter together), his depression got worse. In 1984, he tried to kill himself by overdosing on sleeping pills and alcohol, an experience he wrote about in 1991 in Fates Worse Than Death , a collection of essays.
