Breeders may not want to admit it and its very hard to get them to talk about it if they are actively breeding, but it is TRUE.
If your contact is only with championship Siamese it may be that those you have talked to may not carry the recessive.
For they kittens I know of personally,
There was only one seal point female and one seal point male with absolutely no other possibility of any other cat contact. They are both CFA registered and have no white of any kind on them anywhere. They are owned by a family member of mine (a breeder) and I saw the kittens born and develop their color. White toes on the two back feet. Once it is said that it happened to us, other siamese breeders have admitted to having white toed kittens from time to time also. This usually is admitted to during a pedigree/purchase discussion.
