Production steadily increased and in 1970, the company was incorporated as "Royal Canin S. A."; a larger factory was opened in Aimargues and began distribution throughout Europe. Forty staff were employed in the annual production of five–thousand five hundred tons of feed. A subsidiary, Royal Canin Iberica, was established in Spain. In March 1972, Cathary sold the company to the Guyomarc'h Group, a much larger, family-run animal feed business founded by Jean Guyomarc’h in 1954, which specialised in livestock feed.
