I had the feeling that this was one of your shots and that I might be critiquing it! Like that you're in profile and cat is more face-on to the camera. The b/w seems to enhabce the feeling you wanted to get, and glad that you didn't go over the top with a 'witchy' outfit. That the cat is black and white only helps break up the stereotype of a black cat as a witch's familiar.
Not so sure about the crop, but hard to see what else might have worked. The high-key lighting seems to work fairly well, and kitty doesn't look too upset at being cast in the role you've given her! It's always a lot of fun to critique your images, keep them coming.
I'd have cropped a bit off the top so it's dark all on the upper left, all along the left and the bottom... Makes it SO much more intimate ... (and I'd have chosen a different title).
I love the way the cat appears to be hugging its owner while staring into the camera. Pay that cat top dollar, cause he/she knows how to pose for the camera :) The black and white work beautifully here. Very nice composition.
I'd have perhaps like'd a slightly less white background.
