Having laid perfectly still this whole time, the cat on the table now moves. It takes you a moment to realize just how it’s moving – and you never fathomed that any animal could pull this trick off, have it with outside help or on its own – at least not a four-legged vertebrate.

The cat is turning inside-out.

This story originates from Royal Road. Ensure the author gets the support they deserve by reading it there.

(Note: inside out adv (ca. 1600) 1: in such a manner that the inner surface becomes the outer. (from Webster's tenth edition).

Basically, the cat's fur is pulling into its ass, while, as part of the same gluey flow, its alimentary canal walls are exuding off of its mouth, the longitudinal conduit through the animal uninterrupted, the dermal and the epithelial a heterogeneous continuity.)
