As the hairs spread up her arm and to the rest of her body, Mary realized that she wasn't dreaming. Her body was growing black and gray fur, like a raccoon!
Something in the seat of her pants caused a sharp pinch. She felt behind her and detected a lump inside of them...and it was growing. She fumbled with her pant clasp and pushed them down her legs, allowing a black and gray striped tail to fly out. It gained length quickly, growing long enough to touch the floor. Its bushy hairs made it soft and thick.
"I've got a raccoon tail?" Mary said, incredulous. The vial she drank was actually working! Her thoughts ran back to the garbage outside, and so did her body as she raced down her front lawn, pantsless. The furred woman rummaged through the garbage until she grasped the box. Pulling it out, she ran back inside once more, barely in time to avoid being seen by a car driving up the street.
She opened it back up, searching quickly for a vial with a picture of a human on it. Her changes continued unabated, as her hears enlarged and grew black fur. On her face, a mask of black hairs rounded her eyes as gray fur filled in the rest of it. The hair on her head darkened to jet black, becoming as bushy as her tail. Her nose flattened and stretched farther out from her face until she could see it clearly in her own vision.
"There's got to be a human vial somewhere..." she said, panicking.
