Most of the time in CFA, a kitten is going to be registered as the same breed as its parents have already been registered – of course, this is assuming that the two parents are the same breed, to start with!
However, there is a somewhat little known exception to that fact – and even stranger, it only works “one way”!
Abyssinians are a shorthair cat. Their “cousins”, the Somalis, are longhaired.
Shorthair is a dominant gene – if they’ve got that gene, they’re wearing it for all to see.
Somalis are allowed to outcross to the Abyssinian “parent” breed, and in that first generation, you would normally get all shorthaired offspring, but they will be registered as Somalis, because they have one Somali parent. Somali registration prefixes are 1380-1381 (ruddy), 1382-1383 (red), 1384-1385 (blue), and 1386-1387 (fawn).
They also have a prefix for the shorthair offspring, but it isn’t separated by colors, as the other prefixes are. Instead, SH Somalis are lumped into 1398 for male shorthairs, and 1399 for female shorthairs. Those SH offspring are not eligible to be shown – well, unless you consider showing an AOV as “showing”. They’re not eligible for titles, other than the DM title.
In the next generation, the Somali breeders are hoping to then get longhairs, as that first generation SH Somali does carry the LH gene, from its one Somali parent; so by breeding it back to another Somali, you would theoretically get 50% shorthairs, and 50% longhairs (trust me, it just doesn’t ever seem to work out that way, though!)
HOWEVER – here’s the exception.
The LH gene that makes the Somali “a Somali” did come from the Abyssinian parent breed, as the result of a recessive gene that was found within the breed. How this gene got there in the first place is a matter of some debate, but nonetheless, it’s there. Somalis were accepted for championship status in CFA in 1979, after several enterprising breeders decided to seek out those Abys that were found to carry that elusive longhair gene, and start deliberately breeding for the longhairs.
So, as was discovered many years ago… it IS possible for two Abyssinians to be bred together, and produce a longhaired offspring! And if this happens, that particular kitten will be registered as a Somali. If there are any shorthair siblings in the litter, they will be registered as Abys in CFA – and they CAN be shown as Abys, and earn titles, as can their “surprise” Somali sibling! The Abyssinian parents will not be re-registered as shorthair Somalis, and they can continue to be shown, earn titles, etc. They will also become VERY popular with the Somali breeders, once they’re found to carry that LH gene!
So… you might ask… what’s the difference between THOSE shorthair offspring (which could carry the LH gene), and the shorthair offspring from an Aby to Somali breeding?
I hope you weren’t expecting an answer to that question…
