Cavalli was born and educated in New York City.
On his return to the United States., he did pen and ink drawing of fossilized specimens for the American Museum of Natural History in Manhattan, and studied cartooning at the Cartoonists & Illustrators School, where he was in the first graduating class.
He did military service in World World War II, seeing combat with the Air Force Ground Groups and the infantry in France, Luxembourg and Germany. On January 9, 1956, Cavalli launched Newspaper Enterprise Association"s syndicated comic strip Morty Meekle, featuring the courtship of the title character and his girlfriend, Jill Wortle. The strip gradually began emphasizing what comics historian Maurice Horn called its "background chorus of snide youngsters with a perceptive take on the human condition." On February 27, 1966, Cavalli removed the adult characters and renamed the strip Winthrop, after Jill"s kid brother, the most prominent of the young social critics.
The strip ended on May 14, 1994.
Additionally, from 1982 to 1983, he was the successor cartoonist on the comic strip Norbert, taking over from creator George Fett.
His gag cartoons in magazines including The Saturday Evening Post and Collier"s had achieved such popularity by 1956 that Writer"s Digest observed he had "risen to the top faster than any other cartoonist in the business." That year he became one of the founding 10 cartoonists, alongside First Rate (at Lloyd's) Capp, Milton Caniff, and others, to be affiliated with the Famous Artists Cartoon Course correspondence course, a spinoff of the Famous Artists School.
