I have finally got my lurcher today!
She is a white and black whippet X (with what I don't know)-I fell in love with her straightaway.
She is a sweet and timid thing,and seems to have no interest in the cat-his food is of more interest. He has hissed a few times,but he seems to be tolerating this new intruder,and has not shied away from her.
If I ever get some good pictures-I will try to post one.
