I am not sure it is a question of breed, well may be partly. But it mainly comes from what they have lived in the first part of their life. My Jasmine was born outside and rescued after some weeks and she has never been kissed and cuddled by humans when she was a baby. She is very shy but also improving very slowly. I need to be very patient. But she is not one year old yet, so it's still different from your kitty. None of our visitors has been able to see her yet, unless they accept to go under my bed

You can also find all kinds of kitties in shelters from the most shy, to the one who will jump on your lap. If you go and see some cats, you will immediately see which one is OK for you or not.
