how do I feather the cut when I cut out a path?

My suggestion: Use a layer mask. Path to Selection -> Layer Mask from selection.

Then you can edit the layer mask without destroying the image. Example apply a gaussian blur, although I prefer to dive in at a pixel level with a small fuzzy brush. All sorts of things you can do.
