Temperament in kittens?

[azulvioleta305]

I have gravitated toward purebred kittens because their temperament is more predictable than domestic breeds (short, medium, long haired). Maybe I am wrong and should consider domestic kittens.

My concerns:
1. shedding (I want a cat with minimal shedding). so, i was considering certain pure breeds and domestic medium/long hair...I heard domestic short hair shed a lot. Is this true? Can I ask the shelter if the kitten sheds a lot? I think they would look at me funny and give me the...they all shed face. I know they all shed, but I know some shed more than others.
2. temperament (I want a calm, social, docile cat. Will asking the shelter about the kitten's temperament suffice? Or will his/her temperament change if he is a domestic kitten?
