The creator of this oddity slowly walked back. Each step he took the cat followed him. He grabbed a lab beacon and threw it at the cat. As if dissolving it, the goo quickly wrapped around and absorbed it. A moment later it stretched and spat out a rubbery black beacon.
"Oh, oh no. Noo, what have I done?"
He kept retreating until he was backed up to a wall. The creature continued, finally rubbing her head against his jeans in the process. A little bit of goop stained them, but otherwise it was adorable.

As John wiped his brow, he saw the goop still covered his hand. In fact it seemed to expand and spread, moving rapidly as it coated him. His entire arm was quickly coated in the rubbery black substance, and as his sleeve dissolved he saw what had become of his hand. It had suddenly become a pitch black shiny paw, just like the cats.
