Selkirk RexSELKRACK Rex
Selkirk Rex is a kitten race with very wavy fur. Selkirk Rex is different from all other Rex-races. In contrast to Devon Rex and Cornish Rex, the length of the head is normally long and not partially absent. The difference to the LaPerm is that the Selkirk Rex fur is plushier and thickier.
Whereas the LaPerm family is a single dominating factor, the Selkirk family (Se) is an imperfect dominating factor; imperfectly dominating allelic couples generate three possible types of genes and phenotypes: heterocygous females (Sese) may have a thicker fur, which is favored in the exhibition ring, while homocygous females (SeSe) may have a narrower hairline and less fur volumes.
Selkirk Rex was founded in 1987 in Montana, USA, with a whelp of a saved cats. Eventually, the only unusual coat in the kittens were placed with Jeri Newman, the grower who gave her the name Miss DePesto (after a curled figure from the TV show Moonlighting by Allyce Beasley).
The cattery was raised with a young Negro-Perserkat, who produced three Selkirk Rex and three straight-haired cats. However, this showed that the genes had an autosomally dominating heredity. Selkirk Rex all go back to the Miss DePesto cats. The name Jeri Newman was given to the race after her step-father "Selkirk", which made it the first (and currently only) kitten race called after a real one.
This race was designed in two fur length, long and shor. It' a large and sturdy race, similar to a Britsh Shorthair. It has a very smooth fur and a wooly appearance with frizzy, untextured horn. The American Shorthair, Persian, Himalayan, Exotic and Royal Shorthair were used as crossbreeds to evolve this cats.
It was recognized by the International Cat Association in 1992, the American Cat Fanciers Association in 1998 and the Cat Fanciers' Association in 2000. All colours of the variety are acceptable, as well as albinist, bicolour, silver/smoke, cuttlefish, minks, chocolate or purple. It has an extreme thick fur and a high scaling tendency.
In contrast to other Rex races with less coat, Selkirk Rex is not suggested for cats. Selkirk Rex's spirit mirrors that of the races used in his evolution. You have much of the relaxed, reserved British Shorthair quality, the cosy Persian character and the playful exotic Shorthair.
The Selkirk Rex race has no known medical problem. They' re a sturdy race. As with other Rex races, the inside of the ears can be irritated by curled coats, which increases the output of earwax. Homozygote females (with two replicas of the predominant Selkirk Rex gene) may have a trend towards excess fatness of the hair, which requires an increase in bathrens.
There are other medical issues that can be passed on from the outside cross races used, which include Persian polycystic kidney disease and British Shorthair hypertrophic cardiomyopathy. Conscientious growers check their kittens for these illnesses to minimise their effects on the cattery. All Selkirk Rex in the UK that have been enrolled in GCCF are either clinically polycystic kidney disease or are from 2 sexually engineered mothers.
Selkirk Rex is characterised by an autosomally dominating, wooly wavy anomaly in the wavy outer layer of heddle. 1 ] A splicing variation was found in the KRT71 genes associated with the phenomenon of wavycoats. The KRT71 is a decisive factor in the keratinisation of the follicles.
It is also found in an allerle of this genes that is also involved in the sphynx (hr) and Devon Rex (re) coat. 2 ] Three changes in KRT71 have now been detected in kittens constituting the allelical row KRT71SADRE > KRT71+ > KRT71re > KRT71hr, where SADRE is the proposed place name for the autosomally dominating rex 21 allele. a...
