The DoF is just a little too shallow. The bridge of the cat's nose is in perfect focus, but the eyes are a bit blurry. Stetting down you aperture 1 stop would probably been enough to fix this.
wow what a cool photo - I don't usually go for the household animal photos but this is my 1st photo i am viewing for the challenge and wow what a start. - 9 great detail and you fill the frame - well done.
