"I can't drink any more!" you tell her "It's gone off, as am I!"
The witch cackles. "You'll be in no fit state to go anywhere!"
Suddenly fur, black fur starts growing all over your body and you start growing whiskers as well. Your pants split in the back as a long black tail snakes out. Your hands turn to prehensile paws, your palms and tips becoming hard pads and your nails turn to sharp retractable claws. The same thing happens to your feet and your shoes split open. Picking up a silver spoon, you are shocked to see that your face in the reflection is that of a cat!
