Technically speaking, you usually will want to focus on the eyes. In #3 the nose is in focus, but not the eyes. I would probably close down the aperture on that shot to get a larger DOF, but if you want the low DOF look, the eyes need to be in focus (for portraits in general, not just animals)
3 is my favorite anyway though because I think it has the best composition. Retake it with the eye focused and I think you'll like the result.
You really don't always need to focus on the eyes, especially when there is something to see on the nose, like the hairs. Not sure if he intended that in this picture though.
