  •  TIMBA registration codes are a modification of the EMS system. The code has been modified to more accurately describe thai cats as they exist in Thailand and intended to be less confusing for thai breeders and pet owners in Thailand.
  • The TIMBA code consists of 6 different parts, the Variety, Coat color, Coat pattern, Eye color, Birthday (MMDDYY) and three unique letters (XYZ) in that order.
  • TIMBA registration codes will appear on all certificates and pedigrees, providing an informative history of your cat.
  • Examples for different colors and patterns can be viewed below.
