|Beautiful photo, gorgeous kitty, and an amazing moment. I'm a little unsure that I like the post processing though.
A few ideas: Were it me, I'd have cranked the warmth up a little and the saturation up a lot. I'd have played with brightness to darken the midtones but leave the highlights bright, to draw more attention to those areas. And since this is advanced editing, I'd probably recolor the eyes to bring more warmth and light to them. Finally, the vignette is pretty harsh, darkening the corners including her ears. If you'd masked out the ears so they were unaffected by the vignette I think it would have added dimension.
