Kalou was born in Oumé.
Like his older brother Bonaventure Kalou, he began his career in local club Mimosas before moving to Europe.
He signed for Feyenoord in 2003 and in 2004, he was loaned to Feyenoord's "satellite club", Excelsior.

Kalou then returned to Feyenoord and played in the Dutch top flight Eredivisie for two seasons from 2004 to 2006.
During his time with the Rotterdam-based club, he scored 35 goals in 67 league appearances, also winning the Johan Cruijff Award in 2005 as the most promising young talent of the season.
Kalou, together with Dirk Kuyt, were affectionately known as "K2" by Feyenoord fans and the Dutch media, a play on the words of K3, a Belgian pop band.

Kalou was linked to several other clubs, including Auxerre, the French team his brother played for.
