I know how hard it is to capture a moment of action like this (and how long you have to wait/what you have to do). Looks like it's movement left you a tad unprepared (crop of the top ear). But very well done.
I like how you got just the nose area of the cat completely in focus. good lighting too. not to dark, but any brighter and it would change the picture too much.9.
A great pose nicely positioned within the frame to provide a strong composition.
Main problem for me on this one is not the slightly shallow depth of field but the plane of focus - which bits you've chosen to focus on. The nearside whiskers and the mouth are out of focus and yet are part of the more interesting elements of the image. I like the range of dark and light backgrounds - the light bit emphasises the shape of the cat, the dark bit shows off the whiskers that are more in focus. That said overall it feels quite dark.
This is great... and I don't even like cats in the least bit. My only problem is that your DOF needs some adjustment. The cats face should be completely in focus IMO.
