When I went to see some kittens, Ultimately I went because of the parents pedigree's..
you can get a pretty good idea of what the babies will turn out like by studying pedigree's & seeing pictures of as many generations as you can...
once you have studied the genetic history then see the babies..
they will look like fluff balls..
Dont Just look at the pelts, look at the overall package.
study the GCCF & TICA required conformation..
If you have a good breeder, they will point you in the right direction..
at the end of the day, you will be showing 'their cattery off through your kitten/queen' so if they are worth theyre salt they will choose you a good quality baby to work with...
good luck...
