In the senior category, Cadot climbed his first World Cup podium with a silver medal in Copenhagen in January 2007, followed a few months later by a bronze on Isla Margarita. He was selected into the national senior team as a reserve for the 2007 European Championships in Ghent and for the following team competitions. He did not take part, however, in the 2008 Summer Olympics in Beijing. He left his formative club, affected by budgetary restrictions, to join the Team Lagardère in Paris, with which he won the team national championship. After a dry spell, he won a silver medal in the La Coruña World Cup in early 2010, but a case of mononucleosis forced him to forfeit. His hopes for the 2010 World Championships at home in Paris were crushed in the first round by Korea's Kwon Young-ho. He was replaced in the team by Julien Mertine and went through a new dry spell.
