Thanks everyone for your help.
I keep thinking I have decided but then I think of the other one and feel bad and go back to the begining!!!
The siamese is just for sale as he didnt quite make show standards.
The other thing I dont understand about the oriental is that the breeder said they would give me a pedigree but how if he is only 3/4??? They do say they have been breeding for 30+ years and just bred this litter to introduce a new colour to their program...
