FIFe Code
The FIFe Easy Mind System (EMS) is a system used to identify cats by codes. The code for a specific color, pattern or other trait is always the same, no matter the breed. The EMS system, which is not a genetically based system, is intended to be both easy and logical. Although not ever code applies to Maine Coons, the entire list is presented here for reference.​
