Well, of all the cat breeds out there, with those kind of ear, face, leg and tail, which breed has that color trait????? The Siamese are the ONLY breed of cat that passes on the trait of any color down to the offsprings, including the offshoot breeds like the Ragdolls, Havanese or anything resembles the Siamese markings. I've had purebreds and Siamese marked cats so somewhere down the line, there WAS a Siamese trait going on.
we have to be careful how we correctly label our Siamese cats. A pure Siamese cat does not have stripes or whorls of any kind on its pointed markings or anywhere in its body. Half Siamese is something that we are seeing more and more of, tabby markings in the body (like mine does because she is not pure, only 3/4 despite what I told her breeders that the father is NOT pure Siamese/traditional head, but has the sealpoint with tabby whorls on his body). Her mother is pure Siamese, papered and all and lovely girl she was and modern type/wedge/bat ears.
So Siamese is and was the fore runner of the "pointed" colors, new or old breed. Now where did the Siamese originated or created from?
We know we have the domestic and modern type of Siamese so with all the "mutts" we got of color pointed, domestic heads prevaiils. I don't think the modern type is dominant in most cases I've seen by Siamese breeders crossing Domestic/modern type cats together and almost all of the litters ended up as domestic type Siamese. Also the "talking" does not carry on in some Siamese, like my last two Siamese, one pure and 3/4 are not talkers. My beloved Bambi was not 100 pure even the parents were papered but she had some faint tabby markings on her legs but traditional but yowl like a Siamese and acts like one.
Mother of chicks, your cat is of Siamese descedent.
