Do you think that Zebedee could have some flame tip siamese heritage?

Zebby has many characteristics of a siamese, such as being talkative, suckling when settling,effectionate and craving human interaction. Some of his physical features, particularly his face, also make me wonder.

This is his sibling Willow, from the same litter but I think they may have different fathers.

Yes, Zebby does have the characteristic points or a Siamese or Colorpoint Shorthair. So, it's certainly possible that he has some of this ancestry. However, the only way to know for sure what a cat's parentage is is to get a cat from a breeder. Zebby is certainly a striking kitty! Do post more pictures of him and Willow.

He seems to be a point, but im not sure what. Creme?  Or perhaps even blue, but having so much white spots on him, he seems whitish... Bro carries much white, so probably he too.  And white covers the other colors...

Different fathers arent necessary.   Say, daddy was a point, momma a tabby with white, but had ALSO a point gene.   Half of the kittens will be pointed, and half not.

Or even, none of the parents is pointed, but both carry the point gene.  One of four kittens will be born as a point, the others will look as their parents.

OK, how old is their siamese ancestry?  Theoretically, it could be even 100 generations back.  But their looks and behavior isnt much alike from a siamese, so they may have a granddad perhaps as Ancestor.

Again, observe the gene must come both from momma and daddy, and be doubled in the individual, to show and express itself.

I adobtef them from a rescue centre. So I'm not sure of there genealogy but a lot of people have said that they have siamese ears and temperament.

I see his tail is creme, so he is a creme point (=diluted red).  But also has white spot on his face, that is why we dont see the masque on face clearly.
