Royal Canin good?

Hey all!! I got to know from a dear friend that Royal Canin is a worldwide manufacturer and supplier of premium dog and cat nutrition. It was founded in 1967 in a village of Gard, France, by the French veterinary surgeon, Jean Cathary. Its headquarters are now located in Aimargues, France. The company was taken over by Mars in 2002. In 2004, Royal Canin acquired the IVD, Medi-Cal and Techni-Cal brands from Del Monte Foods for $82.5 million. What more? is there any more info and the information on it. Gimme some info out of it! Thanks!!!
