In many countries, Thai cats and classic Siamese are constantly mixed up, as there is confusion in these concepts. In addition, for example, there is a Thai cat in the WCF system, but there is no classical Siamese as a breed, but they are often knitted together. And since when mating a Thai cat with a classic Siamese, extreme traits are much more easily fixed in the offspring than traditional ones (roughly speaking, there will be more long-mouthed kittens in the litter than short-mouthed ones), and the population of Thais in European countries is much more similar to Siamese from 60-70 years of the last century. At the same time, there are European nurseries where they try to preserve just the traditional Siamese type.
Today, there is already a sufficient number of Thai cats of different lines in order to think about closing the breed, that is, not allowing animals without pedigree to breed. Now you can certify a cat without documents if it is phenotypically Thai (that is if it is “similar” to Thai). And many owners of pets of color-point color carry them to exhibitions and receive certificates of compliance with the Thai breed. Sometimes in this way, a real diamond gets into breeding, but most often together with a certified cat, we get big problems that are found in the next generation, or even in two or three: white spots, too soft coat are obvious signs of impurities of other breeds. Despite this, Russian breeders managed to achieve a stable population of Thais. True, it should be noted that in different cities Thais differ from each other, but all these differences do not go beyond the standard. The majority of Thais participate in exhibitions according to the WCF system, but the breed is also accepted in other systems, and there are standards for it – MFA, FFE, TICA, LOOF, ICU, GCCF. There are also many independent clubs in Europe that have traditional or classic Siamese. In general, there are many options for standards, and they are somewhat different from each other. Moreover, in many standards, Thai can be mated with modern Siamese, and tail correction is also allowed, which is considered a marriage in the WCF system. I think that all standards have a right to exist, as well as various types of Thai cats. Each breeder chooses the most suitable type of Thai cat for himself and moves in this direction. Moreover, the judges do not have a single vision of the Thai breed, as the owner of the Thai cat becomes convinced as soon as he starts walking with his animals to exhibitions. Sometimes it comes to the point of absurdity: what one judge considers to be dignity in a cat, the other rejects and advises removing the cat from breeding.
The breed standard is the idea that every breeder strives for. And like any ideal (remember the canons of beauty that change from generation to generation), the standard tends to change, reflecting the tendency to breed one or another time. This becomes especially noticeable if we trace how the standard of a cat from Siam changed at the beginning and at the end of the 20th century.
The first standard of Siamese cats appeared in 1889 in the book of Harrison Weir, Our Cats and Everything About Them. Harrison Weir was an expert and organizer of the world’s first cat show at the Crystal Palace in London in 1871. In the chapter “Siamese cats” he not only gives a description of the Siamese cat but also gives her drawings. Weir was an artist, and his book was framed by his own illustrations. In the same book, a rating system (scale) is given, from which we see that the most important in the standard were body color and markings (20 points each) and eye color (also 20 points).
