I've noticed that little kitty's fur looks more like a bib instead of her natural fluff.  Back to the good photo.  I select the edge area of the fur.  I then paste it on the image I am working on and rotate 10 degrees to the right again.  I didn't resize the piece as I wanted it to actually cover a bit more area.

I then use both the clone brush and the soften option of the Retouch Tool to blend the fur in.  When using the clone brush, work with the size and opacity.  In small areas like this, I was mostly using a brush size between 5 and 10 pixels.  If I wanted the clone to not intrude as much, I adjusted the opacity down to something like 70%.

Then I went back and took some of the whiskers too and pasted them on using the same methods as for the fur.  Now I'm tempted to say I did this on the left side, but it's actually the right side of the kitty.  I'm lucky that the fur on my right, her left, is hidden behind the door.  But I do want a little bit more whiskers.  So I go back to the good photo and select a little of the whiskers from the right side.

To stretch the whiskers out a bit, I use a paint brush with the opacity turned down some so it's subtle.  As I extend the whiskers, I continue to bring the opacity on the paint brush down a little.  And there we have my final fix of the kitty, and she's looking really good now.  It's time to fix up the rest of the image, the background.

This won't hurt a bit.  The hard part has been done.  Rebuilding the little kitty was pretty tough because it was the main focus of our photo and it had to look as perfect as possible.  We can pretty much just sail through fixing the rest of the photo.

Since this was a photo we took, I know how the background actually looked.  It was a brisk fall day, and the leaves were bright and colorful on the green grass.  Due to the fact that we were facing into the sun when we took the photo, those colors became over exposed and pretty much lost.  Making the background darker is not going to restore the lost color and detail.  So I go back to the good photo and select a few things.  I select a patch of fall leaves and a patch of grass.  I paste them on my work in progress and rotate them correctly.  Don't worry if they look a bit out of place at first.  We're going to fix that.  Don't forget to rotate though, or that would look too strange!

Below is a little mapping of what and where things will be going on.  I'm putting leaves where the sun washed out all detail, and grass below the leaves.  Use the clone tool and the soften option off the Retouch Tool to blend and overlap until the lawn is filled in.  Adjust the clone tool with a larger size to clone in the white area to the left and top of where you pasted in the leaves.

Now instead of just trying to darken the rest of the lawn, we are going to use the Saturation option of the Retouch Tool.  I set my foreground color to green and test out an area on the left.  You'll have to adjust the opacity and brush size until it looks just right, then touch up all of the lawn and the plants on the right side.
