Rare and Illuminouse!


What about Rare EMS code 12?

The Black Shell Tipped Code 12, the Extreme Chinchillas Shell and the Golden Copper radiant coats are extremely rare, highly sought after and prized. 

We breed the Silver & Golden Shell kittens with less visible tipping markings, also known as extreme chinchilla with 'ultra-wideband'

The tipping is restricted to only the tip of the tail and virtually invisible on the ears, ~It MUST be visible. The top of the coat is clear of any stripped 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.

In the adult Silver, there will only be slight visibility of the black tipping along the tail, ears tips and the paw pads remain snow white - the cat should look white with only a sprinkling of dark tipping 1/5 of the tips. In the golden the tipping is only visible at the tip of the tail, 1/5 of the tips of the fur along the ears and hardly visible on the back. If the fur around the paw pads is dark in colour, along the paw hock and the tummy is not light cream or white - it is not Shell.

A good stud cat in this colour code will fetch £5000 - £10000, kittens starting price is £2000 - and pointed lines £3000. They are highly sought after worldwide and are prized to the connaisseur.

More examples of these radiant coats can be seen on our Coat Colours Page.

Club Recognition
While Fife does not recognise code 12 - it is described as 11 on the Pedigrees. Look out for the top of the coat - a true 12 will have very light tipping on the coat along it's back. 

Golden Cat that is ny12 - is on FiFe pedigree ny11 - (in pointed ny1233 is FIFe ny2133)
Silver Cat ns12 - is on FiFe pedigree ns11 - (in pointed ns1233 is FIFe ny2133)

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. 

The hierarchical order: Ticked(25)> Shaded(11)> Shell(12)

The Genetics
What makes the Shaded and tipped (shell/chinchilla) is derived from the dominant Inhibitor gene (silver) + presence of Wide Band (wb++) + the Ticked Tabby pattern. In silver cats the dominant Inhibitor is present. In golden cats, the dominant Inhibitor is absent. 

Golden chinchilla (ny11/12) - i/i, Ti/-, Wb/Wb
Golden shell (ny12) - i/i, Ti/-, Wb/-

Silver chinchilla  (ns11) - I/-, Ti/-, Wb/Wb
Silver shell (ns12) - I/-, Ti/-, Wb/-

Hierarchical Order : No wb>Wb>Wb+>Wb++
No wideband = Ticked cats ny25
Wb (normal) = shaded ny11
Wb+ (intermediate) = Chinchilla/Shell
Wb++ (greater) = Tipped marking vanish exept for tail (extreme chinchilla and Copper in Golden Cats)

Beyond Copper?
While not recognised by most clubs, an emergence of bleaching tones termed Sunshine in cats has surfaced from selective breeding. Not to be confused with the amber (EMS nt) type also in development.
Hierarchical Order: Golden>Copper>Sunshine

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.
