That's a pampered kitty. The curve of the tail and the curve of the "thingie" make for a nice S across the bottom. I also like the hard backlight for this subject.
For some reason this reminds me of a shot from maybe the 60's or 70's - everything is there, the interest, the shape, even some fine detail - but there is also a certain starkness, even harshness with the blocks of dark and light. I guess there is almost a Lith like quality to it.
