Just be patient, my lil Lexie another black kitty was much the same when she came to live with me, it was suprising because at first she was friendly as can be rolling over having her tummy tickled etc, but then she took to hiding under my daughter's bed for almost a week, she is still timid but that is just her nature, but she is a wonderful pet, your lil blackie will be just fine in time., just be gentle and patient with kitty, I always imagine how i would feel if i were taken to a strange house, i would be scared too.
