In this wonderful world the cat chooses only to focus upon those things of interest.  
The picture is comprised of four key layers:   Layer four uses the cat's image to create a shadow by reversing the image, decreasing its exposure, utilizing free-transform for sizing, lowering its opacity and using a blur filter.   Layer three is the cat's portrait.  Layer two is another picture entirely, a background scene using a radial blur filter but with parts of the scene erased to show the original definition below on layer one, the background image.
