Lovely moggy! When I was about ten years old we adopted a feral kitten from the local steelworks, a black ball of teeth and claws which spent it's first week under the sofa grabbing ankles and spitting.
When he eventually came round, he turned into the most marvellous lap cat, a real sweetie.
It looks to me like you've scored a real beauty, best of luck with her! :)
