Miksi siamilaisissa kissoissa on niin erinäköisiä yksilöitä?

Eikö ne olekaan yhteen kiinnittyneet? !

Samaa olen luullut.

Lienevät alunperin sekoitus useampia rotuja. Siitä se variaatio yleensä tulee.

"pidempi malli" on näyttelylinjainen, lyhyempi taas perinteinen.

Siamilainen on hyvin puhdas rotu, eikä mikään sekoitus. Variaatio tulee siitä, että toiset kasvattajat (vähemmistö) kasvattaa näyttelylinjaisia siamilaisia ja toiset taas perinteisiä siamilaisia jotka ovat alkuperäisen siamilaisen näköisiä. Nuo kolmiopäisemmät ja pitkävartaloiset ovat siis kehitetty vasta 50-60-luvuilta lähtien, kun taas perinteinen siamilainen on hyvin vanha rotu.

Noita perinteisiä kasvatetaan varmaan lähinnä Thai nimellä, ne eivät täytä nykysimskun standardivaatimuksia ja sellaisia etä löydä, jos etsit kissaa siamilaiskasvattajien sivuilta tai näyttelyistä.

Standardinmukaisillakin siamilaisilla on ulkonäköeroja, toiset ovat enemmän extremejä, korvat ovat suuremmat ja alemmas sijoittuneet ja toisella korvat ovat kohtuullisemman kokoiset, mutta näitä variaatioita näkee sitten jo näyttelyissä ja kasvattajien luona.

Tässä "normaali" siamilainen http://cf.ltkcdn.net/cats/images/std/142061-400x267-Blue-point-show-Sia…

ja tässä vähän suurikorvaisempi:  http://www.thecatsite.com/content/type/61/id/191213/width/1000/height/1…

Lisäksi simskuja kasvatetaan joko niin, että ne ovat puhtaita siamilaisia, eli niiden sukutaulusta et löydä muita kuin siamilaisia (LO-rekisteri) tai sitten niin että niiden sukutaulusta voi löytyä mtös sisarrotuja eli itämaisia kissoja. (RX-reksiteri)

The carefully refined modern Siamese is characterized by blue almond-shaped eyes, a triangular head shape, large ears, an elongated, slender, and muscular body, and point colouration. (Aside from the colouration, it bears little resemblance to the original stock, and the more moderate, traditional or "old-style" Siamese, with a much rounder head and body, has been re-established by multiple registries as the Thai cat.)

History

The pointed cat known in the West as "Siamese", recognized for its distinctive markings, is one of several breeds of cats from Siam described and illustrated in manuscripts called "Tamra Maew" (Cat Poems), estimated to have been written from the 14th to the 18th century.[2] In 1878, U.S. President Rutherford B. Hayes received the first documented Siamese to reach the United States, a cat named "Siam" sent by the American Consul in Bangkok.[3] In 1884, the British Consul-General in Bangkok, Edward Blencowe Gould (1847–1916),[4] brought a breeding pair of the cats, Pho and Mia, back to Britain as a gift for his sister, Lilian Jane Gould (who, married in 1895 as Lilian Jane Veley,[5] went on to co-found the Siamese Cat Club in 1901). In 1885, Gould's UK cats Pho and Mia produced three Siamese kittens—Duen Ngai, Kalohom, and Khromata—who were shown with their parents that same year at London's Crystal Palace Show. Their unique appearance and distinct behaviour attracted attention but all three of the kittens died soon after the show, their cause of death not documented.[6]

By 1886, another pair (with kittens) was imported to the UK by Eva Forestier Walker (surnamed Vyvyan after 1887 marriage)[7] and her sister, Ada. Compared to the British Shorthair and Persian cats that were familiar to most Britons, these Siamese imports were longer and less "cobby" in body types, had heads that were less rounded with wedge-shaped muzzles and had larger ears. These differences and the pointed coat pattern, which had not been seen before in cats by Westerners, produced a strong impression—one early viewer described them as "an unnatural nightmare of a cat." Over the next several years, fanciers imported a small number of cats, which together formed the base breeding pool for the entire breed in Britain. It is believed that most Siamese in Britain today are descended from about eleven of these original imports. In their early days in Britain, they were called the "Royal Cat of Siam", reflecting reports that they had previously been kept only by Siamese royalty.[8] Later research has not shown evidence of any organised royal breeding programme in Siam.[2] The original Siamese imports were medium-sized, rather long-bodied, muscular, graceful cats with moderately wedge-shaped heads and ears that were comparatively large but in proportion to the size of the head. The cats ranged from substantial to slender but were not extreme in either way.

Traditional Siamese versus modern development

In the 1950s–1960s, as the Siamese was increasing in popularity, many breeders and cat show judges began to favor the more slender look. As a result of generations of selective breeding, they created increasingly long, fine-boned, narrow-headed cats; eventually the modern show Siamese was bred to be extremely elongated, with a lean, tubular body, long, slender legs, a very long, very thin tail that tapers gradually into a point and a long, wedge-shaped head topped by extremely large, wide-set ears.

By the mid-1980s, cats of the original style had largely disappeared from cat shows, but a few breeders, particularly in the UK, continued to breed and register them, resulting in today's two types of Siamese: the modern, "show-style", standardized Siamese, and the "Traditional Siamese", both descended from the same distant ancestors, but with few or no recent ancestors in common, and effectively forming distinct sub-breeds, with some pressure to separate them entirely.

In addition to the modern Siamese breed category, The International Cat Association (TICA) and the World Cat Federation (WCF) now accept Siamese cats of the less extreme type, and any wichianmat cat imported directly from Thailand, under the new breed name Thai[9][10] Other, mostly unofficial, names for the traditional variety are "Old-style Siamese", "Classic Siamese", and "Applehead" (originally a derogatory nickname coined by breeders of modern-type Siamese).[11]

Aito siamilainen on tuo kakkonen. Ykkönen lienee "Thai siamilainen", mutta rekistöröityjen kissojen vitos kategoriaan kuuluu siamilaiset jotka ovat noita isokorvaisia yksilöitä. Siamilaista usein jotkut käyttävät tuon värityksen takia, mutta ei ole kuitenkaan aito siamilainen. Siamilainenhan on itämainen rotu.

Vanhanajan siamilaiset ovat selvästi eri näköisiä kuin perus siamilaiset
