Neat shot. I like the angle and the use of greyscale here. I do think the blur is a little much, though. A softening retouch would do better than a blurring, if it was intentional. Not much you can do if the cat was moving though, unless you can capture a similar shot.
I received a comment request for this shot. Good subject and good composition. I'd have to agree about the focus; it's not very apparent with the small view but does become overwhelming in the large view. Good attempt, next time try using a faster shutter speed if you have that ability.
