Heh. Perfect capture. There's so much emotion in the kitten's face. From it's wide, bright eyes, to the way it's mouth opens... The combination of the cuteness and the expression is wonderful and just puts a smile on your face.
The focus is a very nice touch to the photo as well. In my opinion, it gives a feeling of the kitten either coming at you or looking up and begging for food for example. To be honest, I don't think I would be able to resist, and I'm a dog person!
