Rare and Illuminouse!
What about EMS code 12?
Lately, we have seen an increase of Tipped Golden & Silver cats with less visible tipping markings. The tipping is restricted to only the tip of the tail and virtually invisible on the ears, ~It MUST be visible. The paw pads, top of the coat is clear of any markings and the underbelly, chin, nose and paws are lighter near white in tone.
The Golden kittens are born radiant orange - it is vibrant and Illuminouse. Silver kittens are born with white paws even around their paw pads. At birth, you should be able to see the dark tipping on the tail and back, white will be visible on the nose, chin & paw pads.
The radiant 12 cat coats are extremely rare, highly sought after.
While Fife does not recognise this code - it is described as 11 on the Pedigrees. Look out for the top of the coat - a true 12 will not have any tipping on the coat along it's back.
Golden Cat that is ny12 - is on FiFe pedigree ny11
Silver Cat ns12 - is on FiFe pedigree ns11
The same principles apply to Blue Golden & Silver - however, it is harder to distinguish and only at 4-5 months can one be certain.
FIFe EMS 12 (Shell) code does not apply to British Short & Longhair - the paradox is that it is not recognised in the Show Ring and can be marked down. However, judges have their own discretion and there is room for movement.
I personally find the tipping (11) the feature that distinguishes the breed colour from other Breeds. It's a hallmark of uniqueness the lighten (12) has rendered the availability of quality Ticked (25) & Tipped (11) Golden British Cats more scarce... once you go down into the polygenes of 11 & 12 it's not possible to go back up to the 25.
The hierarchical order: Ticked(25)> Shaded(11)> Shell(12)
