I agree with you and mugsy re: growling. In fact, isn't it to be expected? We know that in the animal kingdom that we deal with are the territorial issues that they have to work out (or don't) but it's just the normal way of meeting each other, isn't it? This person seems to want perfection right away so if she does adopt Sienna, well, you know! Make sure she has your number before bringing her elsewhere! Sienna is gorgeous but I still am having a soft spot for Coco....too...He's so pretty and smart and possibly homeless too!
