First off, I think we need to define our terms. There are two commonly used phrases to indicate unproductive work around writing: "catwaxing" (or "cat waxing") and "cat-vacuuming."
While both of these terms are etymologically similar ("I can't write right now: I have to vacuum my cat") and both indicate displacement activity ("any work but the work we should be doing" [Monette, 2005]), there are some differences in how each is used. Generally, in this author's experience, cat-vacuuming is the work one feels one must do in order to get ready to write--the washing of dishes, walking of dogs, sorting of pencils, scrubbing of the bathroom grout--whereas catwaxing is more properly reserved for the work one does in place of writing, which one can somehow justify as writing-related.
In exemplia, catwaxing behaviors may include blogging, drawing maps, rearranging post-it notes stuck to the wall of the den in a more pleasing pattern while claiming to be "working on one's outline," and so forth. With the advent of Twitter and the #wip hashtag [Lake, 2009] the actual act of working on one's novel can be subsumed into catwaxing activity.
The worm Ourbourous has turned full circle. The cat waxes itself.
