Hello Aika,
Theoratically cats can have 9 traits.
A non genesis fur is a trait as well as non genesis eye.
Also the shape of the eye if it is not curious but mysterious is a trait and a small pupil is a trait.
Non genesis ears are a trait and a non genesis tail.
As for the shade everything but normal is a trait.
Obviously traits or the amount of traits is not the only thing appealing to a potential customer but just as well a nice combination of traits & fur.
To learn more about traits and their dominance order and how the genetics of KittyCatS work I would like to suggest to have a look at the Google Docs Saga Felix made with the help of the KittyCatS community.
It is a great resource:-)
